The operations are in the wrong
order. Use the letters to list them in the
correct order. (A) Exponents. (B) Multiplication and
division. (C) Groupings. (D) Addition and subtraction.

To answer this question, we need to
recall the order of operations, which enables us to simplify and evaluate numerical
and algebraic expressions. One way of remembering this order
is using the acronym PEMDAS. The P stands for parentheses, also
known as brackets. The E stands for exponents or
indices. The other four letters M, D, A, and
S stand for the four operations of multiplication, division, addition, and
subtraction. It is worth noting that it is
common to write the order of operations as shown, where we group multiplication and
division into stage three and addition and subtraction into stage four.

Looking at this question, it is
clear that option (C), that is, groupings, or parentheses, come first. Next comes option (A),
exponents. Stage three in the order of
operations is multiplication and division. Finally, we have addition and
subtraction. The correct order is therefore (C),
(A), (B), (D).
