Significant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value. We start counting significant figures at the first non-zero digit. Calculate the number of significant figures for an assortment of numbers. Created by Sal Khan. 7⁷ → 4. Our pattern here is 0, 4, 4, 0. Once again, we can see this as a block of 4. Dividing the exponent by 4 and having a remainder of 1 or 0 means the tens digit will be 0. Dividing the exponent by 4 and having a remainder of 2 or 3 means the tens digit will be 4. 1993 divided by 4 yields a remainder of 1.Intro to multiplication.
