I do not understand this question, so these are a few possible equations that you might mean:

10x8x12=80

(10x8x1)2=160

(10x8x1)2=6400

Q: 10 x 8 x 1 2?

(2 x 10^8) + (8 x 10^7) + (1 x 10^6) + (4 x 10^5) + (2 x 10^4) + (1 x 10^3) + (9 x 10^2) + (0 x 10^1) + (6 x 10^0)

I assume you mean, ( parentheses!!!) X/2 + 4 = 10 multiply through by 2 2/1(X/2 + 4 = 10)2/1 X + 8 = 20 subtract 8 from each side X + 8 - 8 = 20 - 8 X = 12 ------------------check in original equation 12/2 + 4 = 10 6 + 4 = 10 10 = 10 ----------- checks

1, 2, 4, 5, 8, 10, 20 and 40: 1 x 40, 2 x 20, 4 x 10, 5 x 8

2.8 =(2 x 1) + (8/10)(2 x 10^0) + (8/10^1)Two and eight tenths

12.8 = (1 x 10) + (2 x 1) + (8/10)
