Math Crosswords

A crossword where every line is a sum. Math Crosswords prints some numbers and leaves blanks, and you drop tiles in until every equation across and down works.

Use the bank as a clue

The tiles in the bank are exactly the numbers you need. If only one large number is left, it has to go where a large result is needed. Counting what is left often solves the last few blanks without any maths at all.

Before you start Math Crosswords

Start with equations that already have most numbers printed.
The number bank is fixed, so each tile you use limits the rest.
A blank where two equations cross must fit both. Solve those early.
Check a finished line with the order of operations in mind. A row can look right and still be wrong.

Playing Math Crosswords step by step

Read the grid
Some numbers are printed. The rest are blanks.
Place tiles
Tap a blank and then a number from the bank, or drag the number in.
Check both ways
Every equation across and down must be true.
Mind the order
In longer equations, multiply and divide come first, so 3 + 4 x 2 = 11.
