Sure! Here are a few examples of simple problems that can be solved in one or two steps using whole numbers:

1. Addition:
   Problem: What is $7 + 5$?
   Solution: $7 + 5 = 12$

2. Subtraction:
   Problem: What is $15 - 9$?
   Solution: $15 - 9 = 6$

3. Multiplication:
   Problem: What is $4 \times 3$?
   Solution: $4 \times 3 = 12$

4. Division:
   Problem: What is $20 \div 4$?
   Solution: $20 \div 4 = 5$

5. Combined operations:
   Problem: What is $(3 + 2) \times 4$?
   Solution: $(3 + 2) \times 4 = 5 \times 4 = 20$
