Multiplying with Negative Integers | Integer Worksheets - Free Printable

Let’s solve each multiplication problem step by step. We’re multiplying positive and negative integers. Remember:

- Positive × Positive = Positive
- Negative × Negative = Positive
- Positive × Negative = Negative (and vice versa)

We’ll go one by one.

K) 25 × (-20) = ?
25 × 20 = 500. One negative → negative.
→ -500

L) -18 × (-33) = ?
18 × 33 = 594. Two negatives → positive.
→ 594

M) -27 × (13) = ?
27 × 13 = 351. One negative → negative.
→ -351

N) -36 × (-18) = ?
36 × 18 = 648. Two negatives → positive.
→ 648

O) 23 × (-7) = ?
23 × 7 = 161. One negative → negative.
→ -161

P) -3.5 × (-4) = ?
3.5 × 4 = 14. Two negatives → positive.
→ 14

Q) -9.3 × 11 = ?
9.3 × 11 = 102.3. One negative → negative.
→ -102.3

R) 16.2 × (-12) = ?
16.2 × 12 = 194.4. One negative → negative.
→ -194.4

S) -22.25 × 5.6 = ?
22.25 × 5.6 = let’s calculate:
22 × 5.6 = 123.2
0.25 × 5.6 = 1.4
Total = 123.2 + 1.4 = 124.6
One negative → negative.
→ -124.6

T) -16.7 × (-16.2) = ?
16.7 × 16.2 = ?
Let’s compute:
16 × 16.2 = 259.2
0.7 × 16.2 = 11.34
Total = 259.2 + 11.34 = 270.54
Two negatives → positive.
→ 270.54
