What is the Order of Operations?

Back

The Order of Operations is a set of rules that determines the sequence in which calculations are performed in a mathematical expression. The acronym PEMDAS helps remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What is absolute value?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction. For example, the absolute value of -5 is 5, and the absolute value of 5 is also 5.

How do you solve (2 + 7 - 1) ÷ 2²?

Back

First, calculate the exponent: 2² = 4. Then, solve inside the parentheses: 2 + 7 - 1 = 8. Finally, divide: 8 ÷ 4 = 2.

How do you solve -8 + (15 - 3) ÷ 4?

Back

First, solve inside the parentheses: 15 - 3 = 12. Then, divide: 12 ÷ 4 = 3. Finally, add: -8 + 3 = -5.

What is the result of -2 x (3 + 8 ÷ 4)²?

Back

First, solve inside the parentheses: 8 ÷ 4 = 2, so 3 + 2 = 5. Then, square it: 5² = 25. Finally, multiply: -2 x 25 = -50.

How do you arrange integers from greatest to least?

Back

To arrange integers from greatest to least, list them starting with the highest value and ending with the lowest. For example, 20, 6, -2, -13.
