In year six we have been playing countdown.

In the game you are given 6 numbers that you have to use to make another, much larger, number. You can use any operation but can only use each number once.

There is a link to the game below if you want to try it.

If you get really good can you help us with a problem? We had the numbers 25, 5, 1, 75, 8 and 50 and had to make the number 440.

Can you work it out?

If you can post a solution, first person gets a prize 😉

    This is what I got for my answer:

    25+75=100
    100-50=50
    50+5=55
    8×55=440
    440×1=440
