What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

In a family, there are five sons. The oldest son is 11 and 3/4 years old, and every next younger brother is younger than the next by 2 and 7/12 years.

Then the fifth son is younger than first son will be

⇒ 4(2 + 7/12)

⇒ 4(31/12)

⇒ (31/3)

The age of the fifth son will be

⇒ (11 + 3/4) – 4(2 + 7/12)

⇒ (47/4) – 4(31/12)

⇒ (47/4) – (31/3)

⇒ 17/12

⇒ 1 + 5/12
