Multiplying by 4 using the doubles strategy utilizes the fact that 4 is double of 2. Hence, 4 time any number is double of 2 times that number.
Thus, given 4 x 8, it can be evaluated using the double strategy as follows 2 x 8 + 2 x 8 = 16 + 16 = 32.

Answer:
Here,
4 × 8 = 32
Now,
using the doubles when multiplying with 4
2 × (4 × 4)
= 2 × 16
= 32
Hence,
we use the doubles this way as by doubling the result obtained on multiplying the 4 with 4
Step-by-step explanation:
Here,
4 × 8 = 32
Now,
using the doubles when multiplying with 4
2 × (4 × 4)
= 2 × 16
= 32
Hence,
we use the doubles this way as by doubling the result obtained on multiplying the 4 with 4
or
double the number 4 i.e 2 × 4 = 8
then again double the result i.e 2 × 8 = 16
and, again double the result i.e 2 × 16 = 32 which the required answer.
