Mathematics / Arithmetic Operations on Numbers

Arithmetic operations are an integral part of our everyday life. We need to know Addition, Subtraction, Multiplication and Division well.  We use these operations during money transactions while shopping, while dividing chocolates and cakes among friends or while organising a school trip, and many more occasions.

Can you think of more scenarios where we use arithmetic operations in our everyday life?

Factoids

Fun with multiplication by 11:
Let us learn an easy way of multiplying numbers by 11:

For 2 digit numbers : Add the two digits and place them in-between the two digits.
Example 1: 27 * 11 = 297
Example 2: 84 * 11 = 924 – For sums greater than 9, carry over the 1 to the previous digit.

For 3 digit number:  Add the first 2 digits and the last two digits and place the sums in between the first and the last digits in the same order.
Example 1: 163 * 11 = 1793
Example 2: 338 * 11= 3718 - For sums greater than 9, carry over the 1 to the previous digit.
Example 3: 274 * 11 = 3014 - For sums greater than 9, carry over the 1 to the previous digit.
Example 4: 584 * 11 = 6424 - For sums greater than 9, carry over the 1 to the previous digit.
