Amy had 23 blocks she gave 7 blocks to isabela and 5 blocks to alexa here are the choices a. (23-7)+5 and b.23-(7+5) and c. 23-7+5 d 7+5-23 i need someone who smart

C seems right

Step-by-step

seems more work then needs be but 7+5= 12 and she originally had 23. so the equation of adding the 7+5 would just be adding up the ones removed together then adding the -23 to the equation is how many Amy had to begin with. so it would be 23-7+5 = 12. others dont seem right since when you add () to an equation that means your multiplying and you wouldn't be multiplying here and for D to be right it needs to be switched around or you'd end up with a - number and she wouldn't have a - number of blocks. just divide up a problem if need be and break it down to smaller parts to make it easier to deal with.
