Answer 3

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

The expression you provided is:

10 + 21 ÷ 3 - 15 ÷ 5 + 9 * 3 + 9 * 2

First, perform the multiplication:

9 * 3 = 27 9 * 2 = 18

Now, the expression becomes:

10 + 21 ÷ 3 - 15 ÷ 5 + 27 + 18

Next, perform the division:

21 ÷ 3 = 7 15 ÷ 5 = 3

Now, the expression becomes:

10 + 7 - 3 + 27 + 18

Finally, perform the addition and subtraction from left to right:

10 + 7 = 17 17 - 3 = 14 14 + 27 = 41 41 + 18 = 59

So, the answer is 59.
