1. The problem is to add two numbers, where the first number is 359 and the second number is 32. 2. The formula for addition is straightforward: $$a + b = c$$ where $a$ and $b$ are the numbers to add, and $c$ is the sum. 3. We add the digits starting from the right (units place): - Units: $9 + 2 = 11$, write 1 and carry over 1. - Tens: $5 + 3 = 8$, plus the carryover 1 gives $9$. - Hundreds: $3 + 0 = 3$ (since 32 has no hundreds digit). 4. Putting it all together, the sum is $$391$$. 5. This method applies to all addition problems with three-digit numbers and smaller numbers. Final answer: $$391$$.
