Front

How do you solve the expression (2 + 7 - 1) ÷ 2^2?

Back

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

Front

What does it mean to evaluate an expression?

Back

To evaluate an expression means to calculate its value by performing the operations indicated.

Front

What is the order of operations in mathematics?

Back

The order of operations is: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right), often abbreviated as PEMDAS.

Front

Determine whether the statement 6[1 ÷ (2^4 - 12 + 2)] = 1 is true or false.

Back

TRUE.

Front

What is an algebraic expression?

Back

An algebraic expression is a mathematical phrase that includes numbers, variables, and operation symbols.

Front

Back

Front

How do you solve the expression 7 x [32 - (3 x 4)]?

Back

First, calculate inside the brackets: 3 x 4 = 12, then 32 - 12 = 20. Finally, multiply: 7 x 20 = 140.

Front

What is the result of 2^3 + 4?

Back

The result is 8 + 4 = 12.
