Learn mental maths, discover practical maths tricks and enjoy brain games with MathWiz. Learn step by step, then use maths games to build speed and understand mistakes.

Explore 25 lessons, 34 worked examples and 19 modes, from mental arithmetic practice to number puzzles.

Learn maths tricks for fast calculation

Build your mental maths foundations with lessons on addition, subtraction, multiplication, division, fractions, percentages, powers and roots.

• Bridge through 10, split numbers and round then adjust.

• Use maths tricks for multiplication: double, halve and break numbers apart.

• Use shortcuts for 5, 9, 11 and 25 in multiplication practice.

• Explore maths tricks for percentages using 10% and 1% anchors.

• Practise fraction equivalents, divisibility rules, squares and square roots.

Every lesson links to a quick round to put new maths tricks into practice.

Mental maths practice that adapts to you

Choose from 8 sections: Addition, Subtraction, Multiplication, Division, Fractions, Percentages, Squares & Roots, and Mixed Operations.

Each topic starts gently and gets harder gradually. Strong addition skills won't make fractions harder.

Choose adaptive Standard, Easy, Medium or Hard. A wrong answer shows the method for solving the problem. Review each session to see what needs more mental maths practice.

Mental maths games for daily practice

• Daily Challenge: five new problems each day.

• Brainstorm: speed maths practice in short, timed mixed rounds.

• Endurance: longer runs that reward steady accuracy.

• Speed Sprint: 60 seconds of multiplication practice with streak multipliers.

• Arena Battle: race against bots in a duel or four-contestant battle.

Fit mental maths training into a short break. These speed maths games reward accuracy as well as quick answers.

Brain games for memory, logic and estimation

Try brain games for memory with Number Memory: recall sequences. In Chain Reaction, keep a running total as operations appear.

Explore brain games for logic with Balance: find the missing value to level the scales. Solve number puzzles in Fill the Grid by meeting each row and column target.

Arrange numbers and signs for high and low results in Peak & Valley. Estimate answers on a number line in Close Enough. These brain games bring variety to daily practice.
