I once cashed a cheque at the bank. I had spent £0.68 before I realised the bank clerk had made a mistake. He had transposed the pounds with the pence. I now had exactly twice the value of the original cheque. What was the original cheque's value?
Using the digits 1, 2, 3, 4, 5, 6, 7, 8, 9, can you make 100?
You can use addition, subtraction, multiplication, and division, as well as brackets.
However, they must stay in the same order and you cannot join two digits to make another number, e.g. 1 and 2 cannot be used together as 12.
Hint: Try this using a calculator.
1 + 2 + 3 + 4 + 5 + 6 + 7 + (8 x 9) = 100.
(1 x 2 + 3) x 4 x 5 + 6 - 7 - 8 + 9 = 100.
-(1 x 2) + (3 x 4) + 5 + 6 + 7 + (8 x 9) = 100.
(1 + 2 + 3 + 4 + 5) x 6 - 7 + 8 + 9 = 100.
(1 + 2 + 3 + 4) x (((5 - 6) x (7 - 8)) + 9) = 100.
