One of the most frequently misunderstood features of the iPhone calculator is its percentage function. Learning how to use iPhone calculator‘s percentage button correctly can save you from common errors. The calculator interprets the percentage button in specific ways depending on the preceding operation.

Step-by-Step Derivation of Percentage Calculations

Let’s break down how the iPhone calculator handles different percentage scenarios:

Calculate X% of Y: This finds a portion of a number.

iPhone Steps: Enter Y, press ‘x’ (multiply), enter X, press ‘%’.

Formula: Result = (X / 100) * Y

Example: 15% of 200. Enter 200 x 15 %. Result: 30.
Add X% to Y: This increases a number by a certain percentage.

iPhone Steps: Enter Y, press ‘+’, enter X, press ‘%’.

Formula: Result = Y + (Y * X / 100)

Example: Add 10% to 50. Enter 50 + 10 %. Result: 55.
Subtract X% from Y: This decreases a number by a certain percentage.

iPhone Steps: Enter Y, press ‘-‘, enter X, press ‘%’.

Formula: Result = Y - (Y * X / 100)

Example: Subtract 20% from 150. Enter 150 - 20 %. Result: 120.
What % is X of Y?: This determines what percentage one number is of another.

iPhone Steps: Enter X, press ‘÷’ (divide), enter Y, press ‘%’.

Formula: Result = (X / Y) * 100

Example: What % is 15 of 20? Enter 15 ÷ 20 %. Result: 75.
