Vedic / Quicker / Shortcut Math ⇒ Topic : What is Negative numbers

Kabir
 
There are numerous ways to understand these. You can think of a ruler:
So for the number 2 – 5, you would start at 2, and then count down 5 until you get to 3. To add, count to the right 3 + 4 → 3, 2, 1, 0, 1 So 3 + 4 = 1. Another way to think of them is a positive number is like being in credit and negative is like being in debt. Let's look at 2 – 5 again. If you had £2 in a bank and you withdrew £5, you will be £3 in debt or 2 – 5 = 3. If you have £3 of debt and you put in a cheque for £4 then you will have £1 in the bank so 3 + 4 = 1.
