Positive and negative number practice for 6th and 7th grade. The first sheet explains each operation with a number line and the sign rules. The practice sheets take one operation at a time, then mix them. Every practice sheet has its answer key on the second page.

Adding is easiest to see as movement: start at the first number, move right for a positive and left for a negative. Subtracting is rewritten as adding the opposite, so 4 − (−3) becomes 4 + 3. That single rule removes most of the confusion about two signs in a row.
For multiplying and dividing, only the signs are new: two numbers with the same sign give a positive answer and two with different signs give a negative answer.
On these sheets a negative second number is written in parentheses, as in 5 + (−8), which is how textbooks print it. Work through one operation at a time before the mixed sheet. For expressions with several operations, see order of operations.
