Contractors Calculator Support

Each mixed number is entered on three separate pads:

• Whole-number pad — the whole part, such as the 2 in 2 3/4.
• Top fraction pad — the numerator, such as the 3.
• Bottom fraction pad — the denominator, such as the 4.

Tap 2, then 3, then 4 to enter 2 3/4 — no slash typing or mode switching. Then choose an operation (+, −, ×, ÷) and enter the next number.

Every pad has its own delete key. Use it to fix just the whole number, numerator, or denominator without clearing the rest of the entry.

Answers are simplified automatically and can be shown as a mixed number, an improper fraction, or a decimal. Open Settings to choose the answer format and decimal display. Key vibration can also be turned on or off there.

Open the calculation history to see previous results. Tap an answer to reuse it in a new calculation. History is stored only on your device.

Long-press an answer and choose whether to copy its mixed, improper, or decimal form.
