Strategies 1a) Picking Numbers Step 1. Pick Simple Numbers and substitute for variables. Step 2. Try Them Out Try out all the answer choices using the numbers you picked, eliminating those that gave you a different result. Step 3. Try Different Values If more than one answer choice works, use different values and start again 1b) Recognition by prolonged and multiple use of Picking Numbers

1a) Picking Numbers

1b) Recognition Use different and easy Number Picks to eliminate any possible integer answers.

2) Back-solving Step 1: Estimate the answer. Step 2: Plug in an answer. Step 3: Keep plugging in till you find one that works. Step 4: Try out all answers. Q. If x is an integer and 2 is the remainder when 3x + 4 is divided by 5, then x could equal (A) 3 (B) 4 (C) 5 (D) 6 (E) 7

3) Elimination
