Add And Subtract In Scientific Notation Worksheet

8 problems

Scientific notation or the standard form is a way of writing numbers. It is usually used by scientists and physicists who are involved in the calculations of very large and very small numbers. Instead of writing 490000000, in scientific notation, we write it as 4.9 * 108. While adding or subtracting numbers in scientific notation, we must keep in mind that the exponents are the same.
