Multiplication is a quick way to add
the same number repeatedly.
Intro duc tio n
For example, 3 × 4 means adding 3
four times (3 + 3 + 3 + 3 = 12).
It helps us count in groups and
solve math problems faster!

Multiplication as Repeated Addition
Multiplication helps
us find the total
quickly when a
number is repeated
many times.
Instead of adding 3 + 3 + 3 + 3 = 12,
we can multiply 4 × 3 = 12.
This means 4 groups of 3 or 3
groups of 4, and both give the
same answer, also known as
commutaive property.

Multiplication as Repeated Addition
For Example: Emma has 5 boxes of chocolates,
and each box has 2 chocolates.
Instead of adding 2 + 2 + 2 + 2 + 2
= 10,
she can multiply: 5 × 2 = 10

Terms Related to Multiplication
Multiplicand:
The number that is being repeated
in multiplication.
Multiplier:
The number that tells how many
times the multiplicand is repeated.
2 × 3 = 6
Multiplicand: 2 (This is the
number being repeated)
Multiplier: 3 (This tells how
many times to repeat 2)
