Version 2.0 brings a fresh new icon and design, a real challenge to test your skills, and six levels of difficulty.
Stuck creating an equation while playing a dice-and-math game like Number Knockout? Enter your dice roll and the number you're trying to reach, and NumberBuilder calculates every possible solution — using addition, subtraction, multiplication, division, powers, and roots.
New in version 2.0: switch to Challenge Mode to test your own skills instead of just getting the answer, and pick from six levels of difficulty. Super handy for teachers and parents helping kids who are stuck. Note: this is a solver and practice tool, not the game itself, and is not affiliated with National Number Knockout or Classical Conversations.
An independent app studio making useful, beautifully crafted apps for parents and educators.
