Subtraction in scientific notation

We subtract the coefficients in scientific notation when the base ten orders of magnitude are equal. Observe the general formula and some examples below:

 

General formula for subtraction in scientific notation

(x . 10a) – ( y . 10a) = (x – y) . 10a

 

  • Example: Obtain the results of the subtractions below:
  • a) 34,567 . 103 – 5,6 . 103 = (34,567 – 5,6) . 103 = 28,967 . 103 = 2,8967 . 104
  • b) 1,14 . 10-2 – 0,26 . 10-2 = (1,14 – 0.26) . 10-2 = 0,88 . 10-2 = 8,8 . 10-3
  • c) 25,4 . 102 – 12,3 . 103 = 25,4 . 102 – 123 . 102 = (25,4 – 123) . 102 = – 97,6 . 102 = – 9,76 . 103  → We had to transform 12.3 to 123 because the order of magnitude chosen for base ten was number 2.
