i was wondering if someone could check the answer i got for this math problem 7+2(5-2*9) = 243

I got -19

I think you're supposed to do the parentheses first...but within that, you're supposed to do the multiplication and THEN the subtraction, and then mult it by 2....then add the 7....someone could check me on that too..it's been a while since i took algebra

7+2(5-2*9)

7+2(5-18)

7+2(-13)

7-26

-19

7+2(5-2*9)

7+2(5-18)

7+2(-13)

7-26

-19
