Anyone who needs to do quick percentage math will find it faster than a regular calculator.• To add X% to Y, use the formula Y × (1 + X/100).• Take away X% from Y: Y × (1 − X/100)• X% of Y: (X/100) × Y • A is what % of B: (A ÷ B) × 100 For instance, 200 plus 15% = 200 × 1.15 = 230. For instance, 150 minus 20% = 150 × 0.8 = 120. For instance, 25 is 25 ÷ 200 × 100 = 12.5% of 200.
