5*4/2 + 10 - 4 = 20/2 + 10 - 4 =10 + 10 - 4 = 20 - 4 = 16

10-1/104 = 10-1*10-4 = 10-1-4 = 10-5 or 0.00001
2X - 4 = - 10 add 4 to each side 2X - 4 + 4 = - 10 + 4 2X = - 6 divide each side by 2 X = - 3 check in original equation 2(-3) - 4 = - 10 - 6 - 4 = - 10 - 10 = - 10 checks

(2 +1/3rd) + (2/3rds) = 2 + (3/3rds) = 2 + 1 = 3
4/.4*(4/4)=10 4/.4=10 4/4=1 10*1=10
(44 - 4) / 4 = 10 4 + 4 + ((4 + 4) / 4) =10 (44/4) - (4/4) = 11 - 1 = 10

10 = 4 + 4 + 4/4 + 4/4 10 = (4*4+4) * 4 / (4+4) 10 = (4+4) * (4+4/4) / 4 Variants of the problem: - with five 4's 10 = 4 + 4 + (4+4)/4 - with four 4's 10 = (4 + 4/4) * sqrt (4) - with three 4's 10 = 4 + 4 + sqrt (4)
5*4/2 + 10 - 4 = 20/2 + 10 - 4 =10 + 10 - 4 = 20 - 4 = 16
39.0625 = 10/4 * 10/4 * 10/4 * 10/4
(44/4) - (4/4) = 11 - 1 = 10 4 + 4 + ((4 + 4) / 4) =10
4 over 10 is the same as 4 divided by 10: 4 ÷ 10 = 0.4
