In Algebra, Pronumerals stand for numbers and follow the same rules as numbers in mathematical operations.
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 are made by adding or subtracting 2 or more Terms.
Example: 3a + 5b + 7c , 4xy – z , 7q + 2, 8( t – 6)
Equations have Equal signs that connect Terms and Expressions.
Example: c = 3a + 5b , u = 4xy – z , s = 6t , r = 8 ( t – 6 )
