Let me work through this subtraction puzzle step by step.
Available digits: 6, 2, 7, 1
The format is: 1_ - _ = ___
So we need to create a two-digit number starting with 1 (like 12, 16, 17) and subtract a single digit from it.
Let me list all possible combinations:
From the digits 6, 2, 7, 1, I can make these two-digit numbers starting with 1:
- 12 (using 1 and 2)
- 16 (using 1 and 6)
- 17 (using 1 and 7)
And I can subtract any of the remaining digits. Let me calculate all possibilities:
If we use 12:
- 12 - 6 = 6
- 12 - 7 = 5
If we use 16:
- 16 - 2 = 14
- 16 - 7 = 9
If we use 17:
- 17 - 2 = 15
- 17 - 6 = 11
Now let me answer each question:
1) Can you make a subtraction fact with an odd answer?
Yes! Looking at my calculations:
- 12 - 7 = 5 (odd)
- 16 - 7 = 9 (odd)
- 17 - 2 = 15 (odd)
- 17 - 6 = 11 (odd)
Answer:
12 - 7 = 5 (or any of the others above)
2) Can you make a subtraction fact with an even answer?
Yes! Looking at my calculations:
- 12 - 6 = 6 (even)
- 16 - 2 = 14 (even)
Answer:
12 - 6 = 6 (or 16 - 2 = 14)
3) What is the fact with the largest answer?
Looking at all answers: 6, 5, 14, 9, 15, 11
The largest is 15.
Answer:
17 - 2 = 15
4) What is the fact with the smallest answer?
Looking at all answers: 6, 5, 14, 9, 15, 11
The smallest is 5.
Answer:
12 - 7 = 5
5) Can you make a subtraction fact with an answer of 5?
Yes! From my calculations: 12 - 7 = 5
Answer:
12 - 7 = 5
6) Can you make a subtraction fact with an answer of 14?
Yes! From my calculations: 16 - 2 = 14
Answer:
16 - 2 = 14
Final Answer:
1) 12 - 7 = 5
2) 12 - 6 = 6
3) 17 - 2 = 15
4) 12 - 7 = 5
5) 12 - 7 = 5
6) 16 - 2 = 14
