Grade: 6-a Lesson: S1-L1

Explanation: The best way to understand measurement is by looking at some examples. Take turns and read each example for easy understanding.

Examples:

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

Step 1a

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 * 81 = 648 - > (1)

Explanation: Multiply the first number by the last digit of the second number we get 648.

Step 1b

Multiply the tens digit (2) of the second number (28) by the first number (81), but shift one position to the left.

2 * 81 = 162 - > (2) (shifted one position to the left becomes 1620)

Explanation: Multiply the first number by the ten digits of the second number, but shift one position to the left we get 162.

Step 1c

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.
