To find equivalent expressions for \( 240 + 168 \), we can rewrite it in various forms:
1. **Simplifying the sum**:
\[
240 + 168 = 408
\]
2. **Grouping**:
\[
240 + 168 = 240 + (160 + 8) = 240 + 160 + 8 = 400 + 8 = 408
\]
3. **Using the associative property**:
\[
240 + 168 = (240 + 160) + 8 = 400 + 8 = 408
\]
4. **Using subtraction**:
\[
240 + 168 = 408 = 500 - 92
\]
5. **Using multiplication and addition/subtraction**:
\[
240 + 168 = 240 + 2 \times 84 = 240 + (2 \times 84) = 240 + 84 + 84 = 324 + 84 = 408
\]
6. **Distributive property**:
\[
240 + 168 = 240 + (200 + -32) = (240 + 200) - 32 = 440 - 32 = 408
\]
7. **Split the numbers**:
\[
240 + 168 = (200 + 40) + (100 + 68) = (200 + 100) + (40 + 68) = 300 + 108 = 408
\]
Each of these methods yields either the simplified value or an equivalent expression that shows how we can manipulate or regroup the numbers while still representing the same quantity.
