**Answer: **

In **the base ten block method** we use boxes for multiplying.

For 1 we use 100-block box,

For 10 we use 1000-block box.

For example: 10 × 4,

For this we need to take 4, 1000-block boxes,

Thus, the have total single boxes = 4000

Which is equivalent to 40.

Thus, 10 × 4 = 40

**By the number line method**,

If we want to find 10 × 4 by the number line method.

Then we will start counting 4 10’s from 0 and 4th 10’s occurs at 40.

Thus, 10×4 = 40

**By the place value method,**

If we want to multiply a number by a number then we will split a number into its place value then multiply each place value by the given number,

For example, 52 × 10

(50+2) × 10

50 × 10 + 2 × 10 = 500 + 20 = 520

Since, all method are easy, but **when we talk about large number then Place value method is appropriate to use,** because we can not count total 10’s from 0 for a large number like 520. Also, for large number applying base ten block method is not appropriate.
