1. Jamar writes 5 -(-6). 4+(-3) = 41. Elena says the result should be 26. Who is correct and why?

Elena is correct

Step-by-step explanation:

5 - (-6) * 4 + (-3)

5 - (-24) + (-3)

5 + 24 - 3

29 - 3 = 26

Start by multiplying (-6) * 4

Then rewrite your equation into 5 - (-24) + (-3)

A negative minus a negative equals a positive so you rewrite your equation to 5 + 24 - 3

Subtract 29 - 3 and you get 26 so therefor Elena is correct
