Adding And Subtracting Scientific Notation Math Antics

The easiest way to make the decimals equal is to make the smaller exponent equal to the larger exponent by moving the decimal to the left. Once the exponents are made the same we can add or subtract the numbers that multiply the common power of 10 keep the common power of 10 then convert to scientific notation in the end. For your example 4 2 10 3 2 9 10 4 you could use 42 10 4 2 9 10 4 for the first step or use 4 2 10 3 0 29 10 3 for the first step.
