# Maths Mate Sheet 5 Question 23 (Term 3 2014)

Prediction: I predict this problem will be about code breaking and patterns.

Read: An archeologist found some ancient numbers written as follows: (I’ll use keyboard symbols instead).

\$\$ For 72        \$%% For 48    and    %&&& For 9   What did \$%%&& equal?

Clarification: None needed.

The Big Question: What did \$%%&& equal?

Mathematician’s Toolbox: Have I seen a similar problem?/Test all Possibilities

Solving: First I used the first clue to figure out what \$ is. Since there were only 2 \$ symbols I halved it and got 36. Then I moved on to the second clue I first took 36 six away from 48 because that ions out the symbol we already know, after that I was left with %% is 12 so I halved it and got 6 for each %. Before I went onto the equation I looked at the third clue. I took away six from nine ,because % is six, and then I was left with the total 3 and 3 symbols so that means & equals 1. Then I added them all up: 36 + 6 + 6 + 1 + 1 = 50.

Conclusion: So the answer was 50.
