just solve the solution(sum is addition and difference is for subtraction)if its easier, try switching the signs (of just the second and third)1) 53 =82)10+6 =163)7(21) =144)11+(15) = 45)99 =06)13+(2) =15however, as you can see, it sometimes makes the equation look worse (such as in number 3, 4)you can try thing of a numberline that goes into the negatives as wellsuch as in number 3, you start off with 7 but need to add 21 to find the suminstead of trying to add this, you can subtract 7 from 21 since this difference is also the same as the number you need for the sum of 7 and a number to be 21im sorry if this is confusing but its kinda hard to explaingood luck and if you have trouble, ask your teacher for more help/better explaining:]

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.
