Operation sequence is a mathematical term. Mainly power first, then multiply and divide, and finally add and subtract. If there are brackets, the calculation in brackets should be carried out first. At the same level, from left to right by position.

What is the operation order when calculating addition and subtraction?

From left to right, add and subtract the same level.

operation sequence

1, the calculation of the same level of operation should be calculated from left to right in turn.

2. For the calculation of two-level operation, the second-level operation is performed first, and then the first-level operation is performed from left to right.

3. When brackets appear in the four operations, calculate the contents in brackets first, and then calculate the contents outside brackets. The operations in parentheses are calculated according to rule 1 and rule 2.

4. When there are multiple brackets in the four operations, the calculation of the innermost bracket is carried out on the outer layer of the step-by-step network until all brackets are calculated, which is outside the calculation bracket.

5. If there is a power, calculate the power first. When performing mixed operations, the numbers in parentheses are calculated first, and the parentheses are from small to large. If there is a power, calculate the power first, and then from high to low.
