How to Use These Practice Problems
The best way to learn the Post Versalog 1460 is through repeated practice. Each problem should be approached using the same method used for real calculations:
- Identify the mathematical operation.
- Select the appropriate scale.
- Estimate the expected answer.
- Perform the calculation.
- Check the result for reasonableness.
Basic Arithmetic Practice
Use the C and D scales to solve the following:
- 4 × 7
- 12 × 3.5
- 25 × 16
- 144 ÷ 12
- 360 ÷ 45
- 875 ÷ 25
CI Scale Practice
Use the CI scale method for the following calculations:
- 100 ÷ 4
- 250 ÷ 5
- 1,200 ÷ 8
- 75 × 0.4
- 48 ÷ 1.5
For each calculation, identify why the CI scale provides an efficient method.
Powers and Roots Practice
Use the appropriate power scale:
- Find 6².
- Find 12².
- Find √81.
- Find √225.
- Find 4³.
- Find ∛125.
Folded Scale Practice
Use the CF and DF scales for calculations involving circular relationships:
- Calculate the circumference of a circle with radius 25 mm.
- Calculate the area of a circle with radius 40 mm.
- Calculate the volume of a cylinder using appropriate formulas.
Trigonometric Practice
Use the S, T or ST scales:
- Find sin 30°.
- Find sin 45°.
- Find tan 45°.
- Find tan 60°.
- Find the angle relationship in a right triangle.
Logarithmic Practice
Use the L and LL scales:
- Find log₁₀(10).
- Find log₁₀(100).
- Calculate a fractional power using LL scales.
- Calculate an exponential relationship.
Engineering Practice
Apply multiple scale techniques:
- A formula requires multiplication, division and a square root.
- A mechanical calculation requires π and a squared dimension.
- A scientific formula requires an exponential term.
- A geometry problem requires trigonometry and multiplication.
