Answer:
11
Step-by-step explanation:
3 squared is 9 and 2×1 is 2
You add last, after doing exponents and multiplying. So last add.
3^2 + 1 × 2
9 + 2
= 11
Generally, if there are parenthesis or brackets or any grouping symbols, do that math first. Then multiply or divide in order from left to right, as you encounter them. Then add or subtract in order from left to right as you encounter them. This is commonly taught as PEMDAS or BODMAS.
