Question

-13.4 - 08.9 = ?

I know I can use a calculator but is it really -22.3? I feel like it's wrong since my friends are saying it's -4.5.

Answer 1

the answer is -22.3

because -13.4- 08.9 , the two numbers are negative. and it can't be -4.5 when the center number is not +, if the center number is plus the answer will be -4.5

Answer 2

It is -22.3

Explanation:

Since it is subtraction, the answer must be smaller than -13.4. -4.5 is bigger than -13.4 so it is incorrect. The answer is -22.3
