On #1, you are adding a negative 5 and negative 3. It is pretty straight forward, just add the 5 and 3 and keep the negative sign in your answer. For #2, because you are subtracting a negative 6, the minus signs cancel each other out, making the problem 10 + 6.#3, if you use a number line, you can figure this out. Starting at -7, count 21 spaces to right since you are adding the 21. Like this: -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17#4, you can use the same number line for this problem...start at 11 and move to the left 15 spaces since you are subtracting. #5, again you can use the number line, but if you are getting to understand how this works...try the math.#6, If you want to use the number line, just add some more numbers on to the negative side, start at -13 and move left 2 spaces since you are subtracting. I hope this helps you understand it better, without just giving you the answers. Good Luck.
