Practice questions
Challenge questions
Chains of three or more integers
Word problems
Real-life contexts — read carefully and identify the calculation needed
Key rules
Adding a negative is the same as subtracting: \(5+(-3)=5-3=2\)
Subtracting a negative is the same as adding: \(4-(-2)=4+2=6\)
For chains, work left to right one step at a time.
