What are equal groups in multiplication?
A group is an equal group if it has the same number of items as all of the other groups. Multiplication means ‘equal groups of’ and is written with a multiplication sign: ‘×’. For example: 4 × 4 can be read as ‘4 equal groups of’ 4.
Does multiplication involve joining equal groups?
Multiplication and division are closely related, given that division is the inverse operation of multiplication. When we divide, we look to separate into equal groups, while multiplication involves joining equal groups.
Which operation is adding equal groups?
Repeated addition is adding equal groups together. It is also known as multiplication. If the same number is repeated then, we can write that in the form of multiplication.

What are some examples of multi-step equations?
Multi-step equations with fractions
| 12 ⋅ 5 y 6 − 12 ⋅ 1 4 = 12 ⋅ 3 y 4 + 12 ⋅ 1 2 12 \cdot \dfrac{5y}{6} – 12 \cdot \dfrac{1}{4} = 12 \cdot \dfrac{3y}{4} + 12 \cdot \dfrac{1}{2} 12⋅65y−12⋅41=12⋅43y+12⋅21 | Multiply each term by 12 |
|---|---|
| y − 3 + 3 = 6 + 3 y – 3 + 3 = 6 + 3 y−3+3=6+3 | Add 3 to each side |
| y = 9 y = 9 y=9 | Simplify |

What does equal groups mean in math?
Equal Groups. You can either divide your total by the number of groups or the number of objects in each group. Or, you can figure out what number times your number of objects in each group or number of groups will equal your total.
