Your result is 484.
What are the original values of the dice?
Solution Red = 2, Blue = 3, Green = 4
Why that's amazing you say. How did you ever figure that out?
Funny you should ask.
Assign variables to the values of the dice; Red = a, Blue = b, Green = c. Now just follow the directions.
Multiply red by 2 2a
Add 5 2a + 5
Multiply this by 5 5(2a + 5) = 10a + 25
Add in Blue 10a + 25 + b
Multiply by 10 10(10a + 25 + b) = 100a + 250 + 10b
Add in green 100a + 10b + c +250
This equals 484 100a + 10b + c + 250 = 484
Subtract 250 from both sides 100a + 10b + c = 234
But the left hand side is the natural form of a three digit number (hundred, tens, ones)
Sooooooooo a = 2, b = 3, c = 4
And we could do this for any three values on the dice. Try it for yourself.
