# Quick math question

## Recommended Posts

Sorry my morning pregnant brain is not working well right now. :)

This is from the Miquon Red book (E-31)

3+3-2+2=?

Both my daughter and I automatically solved it like this...

3+3=6. 2+2=4. So 6-4=2

But wouldn't the order of operations say that it needs to be solved like this...

3+3=6. Then 6-2=4. Then 4+2=6

Just want to make sure before I correct her. I can later dig through my olders math books to check if needed, but I just wanted to double check with you guys. Apparently my mind isn't working well enough to teach math today, lol. At least today is mostly review. :)

All addition and subtraction operations are worked sequentially left to right.

Yes, your pregnant brain is right! Left to right with addition and subtraction, since you don't have any parentheses.

ETA: I think the quick "automatic" way I'd explain to my child is that you'd quickly see the -2 + 2 at the end cancel each other out, and just have to compute the 3+3.
