How do you multiply with negative numbers?

Ignore the negative signs. Multiply normally. Then count the negative signs. Odd=Negative answer. Even=Positive answer.

What happens if you multiply by -1?

The number changes to its opposite.

What is a coefficient?

A number attached to a variable.

What are the steps of like terms?

First do keep-change-opp. Then combine terms with the same variable. Lastly, combine constants.

What are the steps of using rates?

First start with the answer unit in the numerator of the first fraction. Then set up the fractions so they cross simplify. Next multiply straight across. Lastly, divide the numerator by the denominator.

What are conversion rates used for?

They are used to convert one unit of measure to another.

How do you solve two step equations?

First you add the opposite of the constant to both sides to create a zero pair. Then divide both sides by the coefficient. If the coefficient is a fraction, multiply by its reciprocal.

How do you prep an equation?

Keep-change-opp, distributive property, and combining like terms.

How do you know what the coefficient is from a word problem?

You know because the coefficient is a rate. It uses words like per, every, and each.

How do you know what the constant is from a word problem?

You know because the constant is a set number.

How do you know what the result is from a word problem?

You know because it is the total. Most of the time it is the biggest number.

How do you solve two step inequalities?

Use the same steps as a two step equation. If the coefficient is negative, reverse the inequality sign.
