Answer 1

Answer:

Step-by-step explanation:

In 5-(-2), we first look at the sign outside the bracket which, in this case, is minus (-). Whenever the outer sign is minus the inner sign CHANGES. So the inner sign which is minus will get changed to plus (+). So it will change from 5-(-2) to 5+2 which is simply 7. At last, we will put the sign of the greater number to the answer. The greater number is 5 which is a positive integer so the answer will also be positive. so the answer is +7.

In 4+(-6), we first look at the sign outside the bracket which, in this case, is plus (+). Whenever the outer sign is plus the inner sign DOES NOT CHANGE. So the inner sign will remain as a minus. So it will change from 4+(-6) to 4-6. I have a trick to solve this but it is a little confusing. Basically, you just subtract the smaller number from the greater number like normal subtraction and then just simply put the minus sign in front of the answer. So when I subtract 4-6 what I actually do is  6-4 and the answer is 2 and then I put a minus sign in front of it which makes it -2.

All other questions are either too simple for me to explain or follow the same rule given above.
