Which options could be the next step in simplifying this expression?
(18 + 23) + 7 Choose exactly two answers that are correct.
A. 18 + 30 (use the associative property)
B. 41 + 7 (use order of operations)
C. 30 + 25 (use the commutative property)
D. 25 + 30 (use the distributive property)
In adding, subtracting, multiplying and
dividing numbers, always remember this rule: PMDAS (or parenthesis, multiply,
divide, add, subtract). The P in PMDAS must come first. We must use an order of
operations. In the problem given, (18 + 23) + 7, they must be added. However you have a
parenthesis that has the numbers 18 and 23. You will add 18 and 23 first and then you will get 41. And so the answer is 41 + 7,
letter B.
