To order the numbers from least to greatest, we need to compare each number and arrange them accordingly:
1. Identify the smallest number:
- The numbers given are: -4, -1, -9, -19, -3, 3.
- Among these numbers, the smallest number is -19.
2. Find the next smallest number:
- After -19, the next smallest number is -9.
3. Continue comparing the remaining values:
- The remaining numbers are -4, -1, -3, 3.
- Among these, the next smallest number is -4.
4. Continue placing the next smallest numbers in order:
- Comparing -4, -1, -3, the next smallest number is -3.
5. Next, compare the remaining numbers:
- Now we have -1 and 3 left.
- The next smallest is -1.
6. Finally, place the largest number at the end:
- The remaining number is 3.
So, the numbers in order from least to greatest are:
