22−4=18
22 minus 4 is equal to 18

4×18=72
4 times 18 is equal to 72

18+18+18+18=72
18 plus 18 plus 18 plus 18 is equal to 72

18+4=22

Answer 1

To determine the total number of tubes of paint the teacher bought, we can analyze the situation:

The teacher bought 4 packs of oil paints, and each pack contains 18 tubes. To find the total number of tubes, we can multiply the number of packs by the number of tubes in each pack:

1. 4 × 18 = 72 (This represents the total number of tubes.)
2. 18 + 18 + 18 + 18 = 72 (This represents adding up all the tubes in each pack.)

Based on this reasoning, the correct equations are:

• 4 × 18 = 72
• 18 + 18 + 18 + 18 = 72

So the two equations that apply are:

• 4 × 18 = 72
• 18 + 18 + 18 + 18 = 72
