Answer:
For the expression 8÷2(2+2), according to the order of mathematical operations, first calculate the expression inside the parentheses, and then perform multiplication and division operations in order from left to right.
- Step 1: Calculate the expression inside the parentheses
Calculate 2+2=4, and at this time the original expression becomes 8÷2×4. - Step 2: Perform multiplication and division operations in order from left to right
First calculate 8÷2=4, and the expression becomes 4×4;
Then calculate 4×4=16.
So, 8÷2(2+2)=16.
