Question

how to simplify a number?

Answer 1

Answer:

Round it off

Create zeros.

So 199 becomes 200.

Round to an order of magnitude

Round a lot, to the nearest "power of ten".

So 218 becomes 100, and 2,180 becomes 1,000.

Slide the decimal point

Compact those zeros created by rounding.

So 200,000,000 becomes 2 x 108 (exponential notation).

Substitute a number you can remember

Instead of rounding, find a nearby number you can remember.

So 218 becomes 222, or 210, or 200, or something else easy.
