**Exercise 8**

Use a concrete representation on a place value chart to perform the following additions.

(a) \( 11_{\text{four}} + 13_{\text{four}} \)

---

**Explanation on Educational Website:**

For this exercise, consider utilizing a place value chart for base four to solve the addition problem \( 11_{\text{four}} + 13_{\text{four}} \). Let's break down each number according to its place values in base four, which are similar to ones and fours (analogous to ones and tens in the decimal system).

1. **Number Representation:**
   - \( 11_{\text{four}} \) consists of:
     - 1 four
     - 1 one
     
   - \( 13_{\text{four}} \) consists of:
     - 1 four
     - 3 ones

2. **Addition in Base Four:**
   - Add the ones column: \( 1 + 3 = 4 \). 
     - Since we are in base four, we convert 4 ones into 1 four and 0 ones.
   - Add the fours column with the carry-over: \( 1 + 1 + 1 = 3 \).

**Result:** The sum is \( 30_{\text{four}} \).

By visualizing this process on a place value chart, the understanding of base four addition becomes more manageable.
