Multiplication is a mathematical operation where a number is added to itself a certain number of times. For example, 3 x 4 means adding 3 four times: 3 + 3 + 3 + 3 = 12.

A multiple of a number is the result of multiplying that number by an integer. For example, the multiples of 3 are 3, 6, 9, 12, etc.

To find the total number of items in equal groups, multiply the number of groups by the number of items in each group. For example, 9 groups of 10 items equals 9 x 10 = 90 items.

To find the total number of people in cars, multiply the number of cars by the number of people each car can hold. For example, 4 cars holding 5 people each equals 4 x 5 = 20 people.

If a number is a multiple of another number, it can be divided by that number without leaving a remainder. For example, 27 is a multiple of 9 because 27 ÷ 9 = 3.

To find the total number of flowers, add the flowers in each vase: 18 (Blue) + 27 (Green) + 36 (Red) = 81 flowers.
