About this app

Hey everyone (specifically students),

See how numbers connect with MathGrid, a visual math companion for exploring arithmetic, number facts, tables, and calculations.

Pick any two numbers on the interactive grid to instantly see their sum, product, difference, and quotient. Choose an operation to transform the grid into a colorful result map, making patterns easier to spot and explore.

Discover useful number facts for every selected pair:

• Greatest common divisor (GCD)
• Least common multiple (LCM)
• Prime factors
• Common multiples
• Modulo

Build confidence with dedicated addition, subtraction, multiplication, and division tables. Choose grid sizes from 10 × 10 up to 25 × 25 to match what you want to study.

MathGrid also includes two independent calculators. Switch each one between a clean everyday calculator and a scientific calculator with powers, roots, trigonometry, logarithms, percentages, memory, constants, random values, and calculation history.

Personalize your workspace with five color themes, seven readable fonts, and adjustable decimal precision.

MathGrid is designed for focused, offline exploration. Your preferences and calculator work stay on your device. No account is required, and there are no ads or subscriptions.
