- IonlyneedpartD.Therestoftheinformationisonlyforreference Expressing numbers using powers of 10 (called scientific notation) has several advantages. First, you can easily tell how big a number is. If a number were written as 3180000031800000, you would have to count the digits to know its magnitude. However, 3.18×1073.18×107 is immediately seen to be somewhere in the neighborhood of 10 million (107107). In addition, the number of significant figures is just the number of digits in the factor preceding the exponent of 10. Since the number 3.18 has three significant figures, so does the entire number 3.18×1073.18×107. If you knew this number to five significant figures, then you would write 3.1800×1073.1800×107. Multiplying numbers in scientific notation When you multiply two numbers in scientific notation, you can multiply the two numbers preceding the powers of 10 and then add the exponents of the two powers of 10.
