# Engineering Notation

Written by Jerry Ratzlaff on . Posted in Algebra

Engineering notation is a way of writing large numbers  $$\large{ 1 2 3, 0 0 0 }$$  into smaller numbers  $$\large{ 1 2 3 \;x\; 10^3 }$$  where the power of 10 is multiplied by 3.

• $$\large{\; 1 2 3 4. 5 = 1. 2 3 4 5 \times 10^3}$$
• $$\large{\; 1 2 0 = .1 2 \times 10^3}$$
• $$\large{\; 1, 2 0 0 = 1. 2 \times 10^3}$$
• $$\large{\; 1 2, 0 0 0 = 1 2 \times 10^3}$$
• $$\large{\; 1 2 3, 0 0 0 = 1 2 3 \times 10^3}$$
• $$\large{\; 1 2 3, 0 0 0, 0 0 0 = 1 2 3 \times 10^6}$$
• $$\large{\; 1 2 3, 0 0 0, 0 0 0 = .1 2 3 \times 10^9}$$
