Daily maths puzzle #4

How to play

Put each number from 1 to 9 in the grid, once each. Every row reads left to right and every column reads top to bottom as a small sum, and each must equal the number at its end.

• Multiply before you add or take away, as in school: 2 + 3 × 4 is 14, not 20.
• Grey squares are filled in for you.
• A total turns green with a tick when its row or column is right.
• Tap a square, then a number. On a keyboard, use the arrow keys and type the number; Backspace clears.

Tips

• Start with the multiplications: a big total usually means big numbers are being multiplied.
• Odd and even help: a row that adds three numbers to make an even total needs zero or two odd numbers.
• Puzzles are easier at the start of the week and harder at the weekend.
