In he came with 5 gold bars and 1 precious diamond.

Because Moneylust is a busy guy and hardly has time to sit around and count all of his riches…[The King reading a piece of paper]
- 00:37
…is there a shortcut he can use to determine how many he has of each item?
- 00:41
You betcha.
- 00:43
Because we are dealing with three occurrences of the same data, we can write it this way: [3 lots of gold bars and diamonds]
- 00:48
Three times 5g plus d… where “g” stands for a gold bars, the 5 that multiplies the

“g” stands for the amount of gold total and the “d” stands for a diamond.

The stuff in parentheses represents what each steward presented to the king… [Stewards holding their gold bars and diamond]
- 01:04
5 gold bars and a diamond…
- 01:06
…and because there were three of them, we can multiply the whole thing by “3.”
- 01:11
To simplify this expression, we can use distributive property. [maths formula scribbled under distributive property]
- 01:14
In other words, whatever is on the outside of the parentheses, we can multiply by each

term on the inside of the parentheses. Three times 5g equals 15g…
- 01:27
…and three times 1d equals 3d. [King wearing 3D glasses]
- 01:32
So we can rewrite the expression as “15g plus 3d.”
- 01:37
Moneylust was a tad displeased when he realized that his stewards had only brought him 15 [The King looking unhappy with 15 gold bars and 3 diamonds]

gold bars and 3 precious diamonds.
- 01:45
He punished them by forcing them to solve this problem. [Stewards solving maths problem as King watches]
