Step-by-step explanation:
Algebra is arithmetic with numbers and letters. Arithmetic consists of the following operations
Addition Subtraction
Multiplication Division
Powers Roots and Logarithms
Addition is repeated counting. Subtraction reverses addition. Multiplication is repeated addition. Division reverses multiplication. Powers or exponents are repeated multiplication. Roots and logarithms reverse powers.
To apply an operation to two letters, write the letters down with the operation between them,
a + b a – b
ab a/b
ab or logba
The answer to an arithmetic problem with letters is an expression. We can also do arithmetic with expressions. Copy down the expressions in parentheses and put the operation between the sets of parentheses.
(2x) + (a + b) (2x) - (a + b)
(2x)(a + b) (2x)/(a + b) or
(a + b)2x or log2x(a + b)
A fraction is the answer to a division problem. If you use the vertical format, the fraction bar acts like parentheses.
