solve -11(-54)-|-25|=

Problem: solve -11(-54)-|-25|= what are the steps to solving this problem. my answers are not coming out corretly. It would be a good idea to address the "absolute value" question first. The absolute value of -25 is 25. Therefore, you are subtracting 25, NOT -25. If you were to get that wrong, you would end up ADDING 25 instead of subtracting. -11(-54) - |-25| = -11(-54) - 25 = Now, multiply. -11(-54) - 25 = 594 - 25 = And subtract. 594 - 25 = 569

Put -5,-4,-3,-2,-1,0,1,2,3 in a 3 square by 3 square grid so each row, column comes to same number.

It helps to start with a traditional magic square using the numbers 1 to 9. Here's one: 2 9 4 7 5 3 6 1 8 The numbers -5 to 3 are to replace 1 to 9 so we subtract 6 from each of the numbers in the above square: -4 3 -2 1 -1 -3 0 -5 2

order of operation

Start with the innermost brackets (10-8)=2; now move the next brackets: 4-2x2+12/6x1, where we substituted the result 2 from the first brackets into its place in the second lot of brackets. So now we do the multiplication and division because they have higher priority than addition and subtraction. So we get 4-4+2 which comes to 2. We are now left with 3x2-6 as the final result and this comes to zero because we multiply 3 by 2 before subtracting 6, and 6-6=0.

how we do this 113-29=84

That's right. 113=100+10+3 and 29=20+9. So when we subtract we are actually doing: 100+10+3-20-9. This can be arranged by grouping the numbers to make the subtraction easier: (100-20)+(10+3-9)=80+13-9=80+4=84. Or 100-20+10-9+3=80+1+3=84. So, the 10 has been removed from 113 and used in the subtraction because we can't subtract 9 from 3 in the ones position without help from the tens. Here's another way of thinking about it. Imagine a set of three drawers. In the top drawer we have the hundreds, the middle drawer the tens and the bottom drawer the ones. We replace the digits with blocks. In this case a block in the top two drawers and 3 in the bottom drawer. But these blocks are boxes. The top drawer box contains 10 smaller boxes which are the same size as the blocks in the middle drawer. And the middle drawer contains 10 even smaller boxes the size of those in the bottom drawer. We come along and we want to take 29 away from what we have in the drawers. Let's start with the bottom drawer with just 3 boxes or blocks. We can't take away 9! So we go to the next drawer and take out the only box in it, leaving the middle drawer empty, and empty all the blocks in it into the bottom drawer so we now have 13 blocks and we can easily take away 9 leaving 4 blocks. Close the bottom drawer. The middle drawer is empty! We need to take 2 blocks or boxes and there aren't any! So we take the box out of the top drawer and empty it into the middle drawer so we have 10 boxes in it. So we remove 2 leaving 8. We are left with nothing in the top drawer, 8 blocks/boxes in the middle drawer and 4 in the bottom. That represents the number 84.

($1.75+2x$0.25+5x$0.05)x24 BODMAS is a mnemonic for the order of operations and stands for, B = brackets O = order or power DM = division and multiplication AS = addition and subtraction B comes before O which comes before DM which comes before AS. We have a bracket in our expression, so we work out its value first. ($1.75+2x$0.25+5x$0.05) within the bracket we have two M operations, 2x$0.25 and 5x$0.05, which come to $0.50 and $0.25. ​This gives us for the bracket, ($1.75 + $0.50 + $0.25) = $2.50 Our expression now becomes, ($2.50)*24 = $48.00 + $12.00 = $60.00 ​Answer: $60.00

subtract 8n from both sides, coming up with a solution of 4n -2 = -10. Then, add 2 to both sides, coming up with a solution of 4n = -8. Divide both sides by 4, coming up with -2. n = -2. Did that help any?

explain complex number and vectors

Start with real numbers. A number line is often used to represent all real numbers. It has infinite length and somewhere we can mark zero, dividing positive numbers (on the right of zero) and negative numbers (on the left of zero). The line is continuous so no real number can be left out. A line is 1-dimensional. A complex number has two components: one real, the other imaginary. A complex number can be represented by a plane, and it's 2-dimensional. So what does imaginary mean? The basis of imaginary numbers is the square root of minus one (sqrt(-1)) and traditionally it is given the symbol i. The square root of any negative number can be expressed using i. So, for example, the square root of minus 4 is 2i, because -4=4*-1 and the square root of 4*-1 is 2sqrt(-1)=2i. A complex number, z, can be written a+ib, where a and b are real numbers. But, more importantly perhaps, they can be represented as a point in 2-dimensional space as the point (a,b) plotted on a graph using the familiar x-y coordinate system. So, just like the number line represented all real numbers like an x axis, so all complex numbers can be represented by a plane, an infinite x-y plane. Now we come to vectors. There is a commonality between complex numbers and vectors. A straight road with cars , houses, people, etc., on it make the road like a number line. Any position on the road can be related to a fixed point on the road we'll call "home". Objects to the right, or eastward, could be in front of home and those to the left, or westward, behind home. The position of an object is the distance from home. This is a 1-dimensional vector field, where all objects have position. If the objects move their speed will have direction, towards the right or towards the left and we can say that a speed to the right is positive and a speed to the left is negative. Now we introduce another straight road at right angles to the first road. Now the picture is 2-dimensional. The position of an object is defined by two values: position east or west and position north or south. North can be positive and south negative. This is equivalent to the complex plane, which represents all complex numbers. The 2-dimensional plane represents all 2-dimensional vectors, whether it's position or speed. But the word "velocity" is used instead of "speed", because velocity includes direction, but speed is just a number, or magnitude, of the velocity. A vector has an east-west (EW) component (x value) and a north-south (NS) component (y value) and a vector r=xi+yj, where i is called a unit vector in the NS direction and j in the EW direction, so the point (x,y) fixes the positional vector r. Vectors are usually written in bold type, so you won't confuse i with i. The magnitude of a vector is sqrt(x^2+y^2) so it is represented by the hypotenuse of a right-angled triangle whose other sides are x and y. Pythagoras' theorem is used to work out the value. The magnitude of a vector is sometimes written |r| and is called a "scalar" quantity, so it doesn't have a direction or a sign (positive or negative), because the sign is a property of the direction of the vector.  A vector is not limited to a 2-dimensional plane. It can have as many dimensions as necessary. An aeroplane's positional vector and velocity would involve another dimension: height. A submarine's positional vector and velocity would involve depth. Height and depth are perpendicular to the EWNS plane and together form 3-dimensional space. The unit vector for height and depth is k, and height would be positive while depth would be negative, and the letter z is used with x and y so that a point in 3-space is (x, y, z). The magnitude |r| is sqrt(x^2+y^2+z^2). When working with vectors, addition and subtraction requires adding and subtracting the x, y, z components separately. When adding or subtracting complex numbers, the same applies to the x and y, real and complex, components. Multiplication and division are a special topic beyond the scope of this introductory explanation.

3 - 3 × 6 + 2 =

  3 - 3 × 6 + 2 =  My friend doesn't believe my answer of -13 In arithmetic caculations, there is a certain order of operations. The rule for this is called BODMAS. Do a google search on that term. For the above expression, all you need to know is that multiplication and division come before addition and subtraction. So what you have is 3 - 3 x 6 + 2 = Since multiplication takes precedence above addition or subtraction, then you do that first. If we carry out the multiplication, then we get, 3 - 18 + 2 = Now we carry out the addition and subtraction operations, in any order. Going from left to right we get -15 + 2 = -13 So your answer is correct
