In Algebra, Pronumerals stand for numbers and follow the same rules as numbers in mathematical operations.

Terms:

Terms may have one or more Pronumerals (Variables ), can be just a number ( Constant ), or a product of  number and Pronumerals where the number is called a Coefficient.

Example :  7x,  13b,  3ab,  9xy,  2

 

 

Expressions:

Expressions are made by adding or subtracting 2 or more Terms.

Example:    3a + 5b + 7c ,     4xy – z ,     7q + 2,     8( t – 6)

 

 

Equations:

Equations have Equal signs that connect Terms and Expressions.

Example:    c = 3a + 5b ,        u = 4xy – z ,        s =  6t ,     r = 8 ( t – 6 )
