How Can I find the sum of -3, -8 and -2?

Answer 1

Add the numbers together -3+-8+-2 = -13

Answer 2

Pretend like you have a certain amount of money, say you spend $3 and $8 and $2. -3 + -8 + -2 means you spent 13..you are negative 13 in your bank account.

Answer 3

I'm not gonna tell you the answer, just how to figure out the problem.

You can find the answer to this problem by adding the numbers together and adding a negetive sign. For example, 12 + 5 = 17. When you add the negetive signs, you get -12 + -5 = -17.

Good luck!

Answer 4

ignore the minus sign, add them all, then add a minus sign to the answer.

3+8+2 = 13

-3 + -8 + -2 = -13

CAUTION: this shirtcut can be used ONLY if all the numbers u want to add have a minus sign. if u want to add one + and one - , example 5 and -8:

SUBTRACT smaller number from the greater number.

in this case, 8-5=3

add the sign of the GREATER number to the result.

the answer is -3

if u want to add -5 and 8, the answer is 3. (sign of greater number 8 is+)

regards!
