Arithmetic Essentials

Building Blocks of Quantitative Reasoning

Arithmetic is the foundation of all mathematical learning, and on the GMAT, it's crucial to master its concepts. Arithmetic covers operations with whole numbers, fractions, decimals, percentages, and ratios.

Key Concepts

  • Addition, subtraction, multiplication, and division of numbers
  • Working with fractions and decimals
  • Converting between percentages, decimals, and fractions
  • Understanding ratios and proportions

Application in Problem Solving

Many GMAT questions wrap basic arithmetic in word problems. You'll often need to convert units, compare quantities, or determine part-to-whole relationships.

Tips

  • Practice mental math to boost your speed.
  • Familiarize yourself with common fraction-to-decimal conversions.

Examples

  • A store increases prices by 20%. If an item originally costs $50, the new price is $60.

  • If you have 3/4 of a pizza and eat 1/2 of what you have, you eat 3/8 of the pizza.

In a Nutshell

Mastering arithmetic is essential for all other quantitative topics on the GMAT.
