BODMAS/PEMDAS PARADOXES
Ex1:
There are no brackets or exponents in the expression.
The division operation has to be performed first.
The division operation has to be performed first.
i.e.,  |
= |  |
| = | 9 – (3 × 3) + 1 | |
| = | 9 – 9 + 1 | |
| = | 0 + 1 (Since addition and subtraction have the same precedence, the operation at the left i.e., subtraction has to be performed first) | |
| = | 1 | |
| Did you figure it out correctly ? | ||
Ex2:
62 ÷ 2(3) + 4 = ?
| 62 ÷ 2(3) + 4 | = | 62 ÷ 6 + 4 |
| = | 36 ÷ 6 + 4 | |
| = | 6 + 4 | |
| = | 10 |
If you worked this way and got 10 as answer,
we fear you are not right.
The correct way is
| 62 ÷ 2(3) + 4 | = | 36 ÷ 2(3) + 4 |
| = | 18(3) + 4 | |
| = | 54 + 4 | |
| = | 58 |
So 58, and not 10, is the right answer !
