Question

Can someone explain what the question is asking me because I’m confused..?

Answer 1

Explanation:

The middle problem is written using Roman numerals:

4 - 2 = 5

By moving one match from the group of two and placing it on top of the "minus" sign, the statement becomes

4 + 1 = 5

which is obviously correct.

Answer 2

the answer should be IV + I = V
