What is the order of operations in mathematics?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed. The acronym PEMDAS is often used: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

How do you simplify an expression with absolute values?

Back

To simplify an expression with absolute values, evaluate the expression inside the absolute value. If the result is negative, take the opposite (positive) value; if it's positive, keep it as is.

How do you evaluate an expression with variables?

Back

To evaluate an expression with variables, substitute the values of the variables into the expression and then perform the calculations.

Front

What is the value of 8n + 5m when n = 4 and m = 2?

Back

The value is 42. Substitute n = 4 and m = 2 into the expression: 8(4) + 5(2) = 32 + 10 = 42.

Front

What is the formula for raising a fraction to a power?

Back

To raise a fraction (a/b) to a power n, apply the exponent to both the numerator and the denominator: (a/b)ⁿ = aⁿ/bⁿ.

What is the value of (2/3)³?

Back

The value is 8/27. Calculate (2/3)³ = 2³/3³ = 8/27.

Front

What is exponential notation?

Back

Exponential notation is a way to express repeated multiplication of the same number. For example, m * m * m * m can be written as m⁴.
