Question

Which symbol replaces ? to make the statement true? 2⋅18−18 ? 2⋅[28−3⋅(2+4)]

A.< B.= C.>

Answer 1

The answer is A.

Explanation:

You have to remember PEMDAS. a good way to remember it is to remember this sentence "Please Excuse My Dear Aunt Sally". please as in perinthasease, Excuse as in exponents, My as in multiply, Dear as in divide, aunt as in add, sally as in subtract. you CAN NOT do add first You need to start with P and go on

Answer 2

The answer is A.< because for the first half 2•18 is 36 and 36-18=18. And for the second half 2+4=6 and 3•6 is 18, and 28-18=10 and 2•10=20. So 18 < 20.
