Using the digits 1, 2, 3 & 4 each once only, and as many +, -, x, / and brackets as you need, try to make as many different numbers as you can, starting at 0, 1, 2 ....

Which is the first number that you cannot make?

Which is the largest number you can make?
How many different ways can you make 10?

Please can you check the following:

(3+2)-4-1=0
(1+4)-3-2=0
(2-1)x(4-3)=1
(4-3)+2-1=2
(4x2)-3-1=4
(4x2)x1-3=5
(4/1)/2x3=6
(4+3)+2-1=8
(4x3)-2-1=9
(3+2)+4+1=10
(4x2)+3-1=10
(1+4)+3+2=10
(4x2)+3+1=12
(2+1)x3+4=13
(4x3)x2+1=25
(2x3)x4+1=25
(1+2)x3x4=36
(2+1)x3x4=36
