Front
when a number outside the bracket multiples with all the terms inside the bracket.
Back
A is greater than B
Front
A > B
Back
Coefficient
Front
A number in front of a pronumeral. If there is no number in front, the coefficient is 1.
Back
Highest Common Factor (HFC)
Front
the largest factor that divides into each term. For example, HCF of 15x and 21y is 3.
Back
Like terms
Front
contain exactly the same pronumerals with the same powers;
the pronumerals do not need to be in the same order, for example, 4ab and 7ba are like terms.
Back
the Difference of a and b is
Front
a-b
Back
Sum of a and b is
Front
a+b
Back
Variables/Pronumerals

In algebra, letters can represent numbers. These letters are called variables or pronumerals
Back
the Product of a and b is...
Front
a x b
Back
A is smaller than B
Front
A < B
