How to show 1200 with two significant figures?

One point two times ten to the three is the correct way to show one thousand two hundred with two significant figures using scientific notation.

Think of significant figures as the number of important digits that tell us how precise a measurement is, and scientific notation helps keep those digits clear. One thousand two hundred written as one point two times ten to the three shows the digits one and two are the only meaningful ones, and the ten to the three just shifts the decimal back to make the original size. If you wrote one thousand two hundred without notation, the zeros would be confusing because they might or might not be measured precisely. Using scientific notation makes sure everyone knows which digits you trust and which are just placeholders.

A common mistake is writing twelve hundred and trying to mark significant figures with unclear zeros, which confuses others, so use scientific notation instead to be exact. Another mistake is thinking trailing zeros automatically count as significant when they are not measured, and the fix is to either use a decimal point and proper notation or switch to scientific notation to show true precision. Some students forget to adjust the exponent when rounding to the desired number of significant figures, and the simple tip is to first round the coefficient to the correct number of digits before writing the power of ten.
