First, what is the largest number you can get using only 2 digits?
Second, can you make 1000 using eight 8′s? Oh, and you can only use addition.
Third, can you place a mathematical symbol between 3 and 7 to get a number which is greater than 3 but lesser than 7?
As ever, please do NOT post your answers, but do say if you think you have solved them and how long it took. Solutions on Monday.
