Here is an easy equation to start off:
17 x 3 + 15 ÷ 3
= we first multiply 17 and 3 then the answer would be 51
51 + 15 ÷ 3
= then we divide 15 and 3 and the answer is 5
51 + 5
= last thing we add 51 and 5 then we get the answer of 56
so the final answer is 56!
17 x 3 + 15 ÷ 3
= 51 + 15 ÷ 3
= 51 + 5
=56!
