WebbThus, the expression 1 + 2 × 3 is interpreted to have the value 1 + (2 × 3) = 7, and not (1 + 2) × 3 = 9. When exponents were introduced in the 16th and 17th centuries, they were given precedence over both addition and multiplication, and could be placed only as a superscript to the right of their base. [1] Webb2x and –5x are like terms. a and are like terms. 6x and 5y are unlike terms. Like terms can be added or subtracted from one another. For example: a + a = 2 × a = 2a (We usually write 2 × a as 2a) 2a + 4a = 6a. a + a + a = 3a. 2a + 4 (Unlike terms cannot be simplified) 4a + 3b (Unlike terms cannot be simplified) 6a – 3a = 3a. 8b – 8b = 0
