using the numbers 24 12 2 7...in any addition subtraction division or multiplication combination, i have to come up with the sum of 24. Help. I have tried every combination i can think of the closest i have come is 22 or 26
assuming you can use the numbers more than once....
24/2 = 12
12*12 = 144
144/2 = 72
72-24 = 48
48-24=24
To find a combination that equals 24 using the numbers 24, 12, 2, and 7 by addition, subtraction, division, or multiplication, we can explore all possible combinations systematically. Let's go through different operations step by step:
Addition and subtraction:
1. Starting with addition: 24 + 12 + 2 + 7 = 45. This combination exceeds the target of 24.
2. Next, we can try subtraction: 24 - 12 - 2 - 7 = 3. This combination is smaller than the target of 24.
3. Let's try different combinations, using subtraction with different numbers:
- 24 - 12 + 2 - 7 = 7. This combination doesn't equal 24.
- 24 - 12 - 2 - 7 = 3. This combination doesn't equal 24.
- 24 - 12 + 2 + 7 = 21. This combination doesn't equal 24.
At this point, we can conclude that there is no combination of addition or subtraction using the given numbers that equals 24.
Multiplication and division:
1. Starting with multiplication:
- 24 * 12 * 2 * 7 = 40,320. This combination is much larger than the target of 24.
- 24 * 12 / 2 / 7 = 48. This combination is also larger than 24.
2. Next, let's try division:
- 24 / 12 / 2 / 7 = 0.1429 (rounded). This combination is much smaller than the target of 24.
- 24 / 12 * 2 * 7 = 28. This combination is larger than 24.
Based on our calculations, there is no combination of multiplication or division using the given numbers that equals exactly 24.
In conclusion, after exploring different combinations of addition, subtraction, division, and multiplication, we can determine that you cannot obtain a sum of exactly 24 using the numbers 24, 12, 2, and 7 with these operations.
