Multiply with the following number:
\$ 81 times 28\$.

Step 1

To multiply 81 by 28, you can use the long multiplication method. Here’s a step-by-step explanation:
Multiply the unit digit (8) of the second number (28) by the first number (81).
\$8 \times 81 = 648\$ - > (1)

Explanation:

Here, we multiply the first number by the last digit of the second number, which gives us 648.

Step 2

Multiply the tens digit (2) of the second number (28) by the first number (81), but shift one position to the left.
\$2 \times 81 = 162\$ - > (2) (shifted one position to the left becomes 1620).

Explanation:

Here, we multiply the first number by the ten digits of the second number, but shift one position to the left we get 162.

Step 3

Add the results from (1) and (2).
648 + 1620 = 2268
So, 81 multiplied by 28 equals 2268.

Explanation:

Here, we add both results we get 2268.
