What is an equation?

Back

An equation is a mathematical statement that asserts the equality of two expressions, typically containing an equal sign (=). For example, 6x + 2 = 10 is an equation.

Front

What is the difference between an expression and an equation?

Back

An expression is a combination of numbers, variables, and operators without an equal sign, while an equation includes an equal sign and states that two expressions are equal.

Front

How do you identify the number of terms in an expression?

Back

To identify the number of terms in an expression, count the number of distinct parts separated by addition or subtraction. For example, in 5x + 3y - 15 + x, there are four terms.

What is the purpose of an equal sign in an equation?

Back

The equal sign (=) indicates that the values on both sides of the equation are the same. It is essential for forming equations.

Front

What are like terms?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and 5x are like terms, while 3x and 3y are not.
