Question

Which expression is equivalent to "5-4"?
5 + 4
5 + -4
4 - 5
4 + -5

Answer 1

I think the answer is 5 + -4.

Explanation:

That's because 5-4 is 1. And 5 + -4 is also 1. 5 + -4 reversed is 5 - 4 (you change the symbol and channge the last number from negative to positive or positive to negative). Sorry if this doesn't make sense or is wrong :3

Answer 2

5 - 4 = 1

5 + -4 = 1
