Practice problems
1. Figure out which of the equals signs has problems in each of these complex equations.
a.
b.
c.
* 2. Fix each of the equations from #1 by making them into shorter one-step equations
* 3. Fix each of the equations from #1 by making them into a complex equation where all numbers are included at each step.
4. What is the primary goal of using true-false equations?
5. Put these true-false equations in order from easier to harder.
a. 8 - 2 = 3 + 3
b. 4 = 2 + 2
c. 3 = 3
d. 2 + 5 = 7 - 1
e. 3 + 4 = 8
6. Which of these missing number equations is trickiest?
a. 4 + 2 = 9 - __
b. 4 + 3 = __ + 2
c. __ - 3 = 2 + 2
* 7. Write a variety of missing number equations (at least 6), each with a different format
* These are hard to put in a D2L quiz, which makes them more likely to turn up on a test.
