If a number does not have a sign, the number is positive.

Multiplication can be shown as: 4×3 4•3 4(3)

In algebra, division is shown with a fraction.

Equal expressions have the same value when all of the operations are completed.

Always think about the order of operations when you write an expression. Use parentheses to show that addition or subtraction needs to happen first.

In subtraction and division problems, order matters. Make sure the symbols match the order of the words.

You will be able to consult the formulas sheet at any time during the math test.

Remember, reading from left to right, positive slopes rise and negative slopes decline.

Remember, you must use both equations to solve a system. Substitute into one and then the other. The order doesn’t matter.

Your answer checks if it makes both equations in the original system true.

With inequality symbols, the small end points to the smaller number.

Small < Large

Use memory tricks to learn the meaning of symbols.

Small < Large

In subtraction and division problems, order matters. Make sure the expression matches the order of the words.

Make sure you think about all the words in a math problem, not just the numbers.

Three dots in a row, like those shown below, indicate that the pattern continues indefinitely.

5, 10, 15, 20, ...

Be careful when you evaluate exponents. Squaring a number is not the same as doubling it.

A number raised to the third power is said to be “cubed.”

Look at both the words and the punctuation in an algebraic expression.

If you finish a problem but can’t find your answer among the choices, check to see if your answer is in lowest terms.

Changing fractions to decimals is time-consuming. Use the calculator to change fractions to decimals.

Problems that ask for a “fraction of” require you to multiply.

of 4 means × 4.

Remember, the order of operations says to multiply before adding.
