Language of Algebra Know how to translate words into algebraic expressions Write out the expression and solve it.

Examples: The sum of 8 and – 7 The product of - 4 and - 6 The difference of 16 and – 8 7 less than 20

Integers Addition - same signs: add and keep - different signs: subtract and keep larger sign Subtraction – change to adding the opposite - always change minus a negative to plus a positive

Integers Multiplication & Division - same signs: positive answer - different signs: negative answer
