## Knowsys Method

**Read the problem carefully. ** If you have never seen this problem type before, it might look strange to you. Don't worry, though. We will show you just how simple these problems are!

**Identify the bottom line.** *c *= ?

**Assess your options. **At Knowsys, we call these problems "symbol problems" because they use fnon-mathematical symbols like stars, hearts, smiley faces, etc. To solve a symbol problem, all you have to do is plug in the information given to you. Use the following steps to ace these problems on the SAT.

1. Write out the symbol problem defined in the question. For instance,

&*a *= *a *+ *2*

2. Directly below that, write out the new version of the symbol problem, aligning the symbol in the original with the symbol in the new version.

&*a *= *a *+ *2*

&*b *=

&*7 *=

3. Substitute the variable(s) or number(s) in the new version for the variables in the original.

&*a *= *a *+ *2*

&*b *= *b *+ *2*

&*7 *= *7 *+ *2* = 9

**Attack the problem. **Let's apply those steps to the symbol problem above. First, write out the original symbol problem defined in the question.
