Wouldn’t it be nice if …..the problem had nice numbers?

Change the “mean” test numbers to “nice” test numbers and then do the problem.

Estimate

Sometimes being close is good enough. Try doing it with nice numbers too.

Just do it

Some problems you just have to do, so just do them!

Plug and Chug

Plug in your own numbers (KISS) and see what happens

Eliminate the Impossible

Use estimation and common sense to rule out the impossible choices.

Only the possible answer will remain.

Using Answer Choices

No need to work for the answer, be lazy!

Use the answer choices and see if the result is true or false.
