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.
