okay, so 32-5+24÷4 is the problem?
first use order of operations. since you have no parenthesis or exponents, you move on to multiplication and division.
24÷4=6
your new equation is 32-5+6.
now you use the addition and subtraction part. since there are both in the equation, you follow the order.
32-5=27
27+6=33.
your final answer is 33. now you have to find the answer that is equivalent to 33.
a.) use order of operations. parenthesis first. 5+6=11. now for the last part.
3×11 is 33, which is the answer you got in the problem.
b and c equal 21, so they do not follow in the equation. however, d is another problem. here is another order of operations. 6×10=60, 3×9=27. now subtract. 60-27=33
the answer is A and D
