+8
6
You can make a number line starting with the number -4 and ending with the number 10. Then start from -4 and count 6 numbers and that will be your answer, which is 2. -4 + 6 =2.
To represent -2 x 3 on a number line, first calculate the product, which is -6. Then, locate the point -6 on the number line, which is 6 units to the left of 0. You can mark this point clearly, indicating that -6 is the result of multiplying -2 by 3.
6 1/2
Visualize a number line. -6 is four to the left of -2. 6 is eight to the right.
0 is the middle number, as below it is -1 -2 -3 -4 -5 -6 and so on, above it is 1 2 3 4 5 6, etc.
-6 > - 7 since we divide to both sides with a positive number such as 2 is, the sign does not change, so that -6/2 > -7/2 -3 > -3.5
6
difference = 4 - (-2) = 4 + 2 = 6
6 = 2 4 5 6 7 9 , 2 and 5 are mirror images, 6 and 9 are rotated
No, the number 2 does not have line symmetry.
(-2) - (+6) = -2 -6 = -8 The difference is one number subtracted from another number. If you relate this question to the number line, it is easier to understand. -l-----l-----l-----l-----l-----l-----l-----l-----l-----l-----l-----l-----l -6...-5....-4....-3...-2....-1.....0...+1...+2...+3...+4...+5...+6 The "distance" between -2 and +6 is 8. But, the direction on the number line in which you are moving does change things. When we subtract +6 from -2, the answer is further to the left on the number line. Plus +6 moves the answer to the right. Plus -6 moves the answer to the left. Similarly, minus +6 moves the answer to the left and minus -6 moves the answer to the right.
