NettetA warning of trickery to be aware of with negative numbers and exponents. NettetTo add or subtract terms that contain exponents, the terms must have the same base and the same power. Otherwise, the terms cannot be added. If the base and power are the same, then the coefficients of the bases can be added or subtracted, while keeping the base and power the same. Given that P and Q are constant coefficients, this can be ...

NettetOnce 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.
