Question

What is the lowest possible number we can get by multiplying any two 2-digit natural numbers?

• A. 10
• B. 100
• C. 110
• D. 9801

Answer 1

The correct option is B 100

The lowest 2-digit natural number is 10.

∴ The lowest number possible by multiplying two 2-digit numbers is the result of 10 $\times$ 10.

So, let us find out the value of 10 $\times$ 10 using partitioning method.

The expanded form of (10 $\times$ 10) is:

Now, let's draw a table and write 10 and 0 on top of the second and third columns and 10 and 0 in the first column of the second and third rows.

Now, we fill the table by multiplying the numbers in the corresponding rows and columns.

At last, we add all the products to get the final answer:
100 + 0 + 0 + 0 = 100


Hence, the lowest possible product of two 2-digit natural numbers is 100.
