1 add 4 is 5 and 2 add 3 make 5. 5 add 5 make 10 so 2 x 10 is 20
(-1)+(-2)=(-3) (-1)(-2)=2
3 * (2 - 1)
25
(3 + 1)2 = 16
4 + 1 - 2 = 3
1 1 1 2 1 3 1 4 2 1 2 2 2 3 2 4 3 1 3 2 3 3 3 4 4 1 4 2 4 3 4 4
It is 3 1/2. To make it simpler, think of it as this:3 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 = 3 1/2
2*6*(-1+3) = 24
(4! - 3)*1*2
3 + 3 + 3 + 3 + 2 +2 + 1 = 17
4+2=6 6-3=3 3-1 2
2 - 1 = 1 1 x 3 = 3 3 x 8 = 24
