1+!+!+2=5, but 1x1x1x2=2. It is just how you put the equation together.
3.5903 and 28.4097 (to 4 dp).
10 and 7 since 10x7 = 70 and 10+7 = 17
you add them together and divide them by 2
-1, -1, -2, -2 works.
-22
-28
They are: 2+4 = 6

2 AND 21 there is only one factor that adds up to 23 and if you multiple 21 times 2 =42
1+!+!+2=5, but 1x1x1x2=2. It is just how you put the equation together.
