September Challenge - Years 5 & 6

The Largest Number

Using the numbers 2, 4, 6 and 8, the multiplication sign, the addition sign and the equals sign, what is the largest number you can make? You may only use each digit and sign once, but you don't have to use all of the signs.

Hint:  The question has referred to the 2, 4 6 and 8 as digits (not numbers) so it is possible to put digits together to make a larger number.  For example, the digits 2 and 4 can be used to make the number 24 (twenty-four) or 42 (forty-two).

Solution:  The biggest number you can make is simply by rearranging the digits to make a four-digit number - 8642.  You don't need to use a calculation.

Well done if you found 64 x 82 = 5248.

July Challenge - Years 5 & 6

Hints:

Remember what product means.
