just think of the negative number as below the zero on the number line. just like the positive numbers are above the zero on the number line. then count out how far you have to go to get to your number. you can also treat the negative number like you a minusing that number take -3 and 7 -3 + 7 = 4 7 - 3 = 4

This occurs when you add a negative number. An understanding of negative numbers and their place in the number line is appropriate for this subject. EXAMPLE : 15 + (-7) = 15 - 7 = 8

Subtracting a negative number is the same as adding a positive number. Also, adding a negative number is the same as subtracting a positive number. -7 + (-5) = -7 - 5 = -12 -7 - (-5) = -7 + 5 = -2

7 because the absolute value of a negative number is how far away it is from zero, hence the 7. hope that helps, if not you can use a number line and count from -7 to 0

No negative 5 is greater than negative 7. Remember, when you go right on a number line the amount of what you have gets bigger. If you go left on the number line the amount you have gets smaller. In terms, think of this. If you were sitting at $-5, how would you get to negative $-7? You'd go left(spend)? So this means that the amount is getting smaller.
The easiest way to find the distance between any two numbers on a number line is the bigger number minus the smaller. Here 23 - (-7) = 23+7 = 30. Remember that minus a negative number is the same as plus that number.
