How to add & subtract numbers in scientific notation?

There are two sets of dividing numbers in scientific notation worksheets.

• Add & Subtract numbers in scientific notation (positive exponents).
• Add & Subtract numbers in scientific notation (include negative exponents)

These are the steps to add & subtract numbers in scientific notation:

1. Make sure that the exponents of both numbers are the same. If they are not the same, adjust one or both of the numbers so that they have the same exponent.
2. Add or subtract the coefficients of the numbers.
3. Keep the common exponent from step 1.
4. Adjust the result to scientific notation if needed.

Example: (3.52 x 10⁵) + (2.6 x 10²)

1. Since the numbers have different exponents, we need to adjust them before adding.

• Adjust the second number to have an exponent of 5: 2.6 x 10² = 0.0026 x 10⁵

2. Add the coefficients: 3.52 + 0.0026 = 3.5226
3. Keep the common exponent 10⁵.
4. The result is 3.5226 x 10⁵.

Example: (4.33 x 10³) − (3.6 x 10⁴)

1. Since the numbers have different exponents, we need to adjust them before subtracting.

• Adjust the second number to have an exponent of 3: 3.6 x 10⁴ = 36 x 10³

2. Subtract the coefficients: 4.33 - 36 = -31.67
3. Keep the common exponent 10³.
4. Adjust the result is -31.67 x 10³ = -3.167 x 10⁴
