Constant Term A constant term is the term in a simplified

algebraic expression which contains no variables.

Division of fraction property

Division of fraction property is basically the amount (property) of the leftover fraction once you’ve divided it. For example; ½ divided by ¼ is 2. You take ¼, take its reciprocal, and multiply it by the other fraction. The answer is the property of the divided fraction.

Equation The equation is basically the problem, the

number model, the or the question and the answer.

Equivalent Equations

Equivalent Equations are equations that are equivalent. Or simpler, the same, equal to each other, duplicate of, and etc.

Inequality Inequality is sort of like the opposite of

Equivalent. It means the opposite, or unequal, not the same.

Integers An integer is just a whole number or

anything else that is not a decimal or fraction.

Multiplication Property of -1

Basically what this is is what property the number -1 holds in the situation that it would be multiplied by something. This would make a number negative, because of the fact that its negative, not positive.

Nested Parentheses

Nested parentheses are parentheses inside each other. This means that you must do what’s inside the parentheses first, then what’s inside the rest of the parentheses first before anything else in the problem. The reason for parentheses is because the answer can come in many different forms.

Open Sentence An open sentence is a sentence is open

when it is not known if it is true or false.

Opposite of a number

The opposite of a number is well, the opposite of a number. I don’t know who better to explain it. For example; the opposite of 1 is -1. The opposite of 2 is -2 and so on.

Order of Operations

The order of operations is the order you do the problem in. A good way of remembering this is “Please Excuse My Dear Aunt Sally”. The picture below will explain how and why.

Reciprocal The reciprocal of a number is the number

flipped. For example; the reciprocal of 2/5 is 5/2. For whole numbers you just turn them into fractions and flip the numerator and the denomenator.

Relation Symbol A relation symbol is a symbol that

represents if a number is equal to, bigger, smaller, or approx to another number.

Repeating Decimals

Repeating Decimals are decimals in which the decimal repeats itself. For example; .1212121212121212, or .5555555555555.

Solution A solution is a solution. The answer to a

problem or question. A solution is a pretty broad and generic word. So the solution or answer to a division problem is the “quotient”. The answer to an addition problem is a “sum”, to name a few.

Solution Set A solution set is a set of solutions. So

basically a solution, but multiple of them.

Terminating Decimals

Terminating Decimals are decimals that come to an end. For example; .75, .25, .5, .125 and so on. Non terminating decimals are .333333333 (and so on), and .66666666666 9and so on).

Trial and Error Method

The trial and error method is basically what it says it is. Its trial and error. You keep trying until you eventually get the right answer. I couldn’t find any pictures online for this. I will give an un-illustrated example then to make up for it. Say your trying to find a multiplication problem for 12, you try 5 x 3, 2 x 8, and so on until you find the right problem. Its trial and error.

Variable A variable is a letter that takes the place for

a number in a sentence. The variable can be anything, or any number. If the variable is “X”, than “X” represents “X”.
