Given:
![4 + 9 + 16 \div 4 - 8 -3 \times 5](https://tex.z-dn.net/?f=4%20%2B%209%20%2B%2016%20%5Cdiv%204%20-%208%20-3%20%5Ctimes%20%205)
To find:
The number of possible solutions, if the Order of Operations did not exist.
Solution:
We have,
![4 + 9 + 16 \div 4 - 8 -3 \times 5](https://tex.z-dn.net/?f=4%20%2B%209%20%2B%2016%20%5Cdiv%204%20-%208%20-3%20%5Ctimes%20%205)
Now,
Case 1:
![[4 + 9 + 16] \div [4 - 8 -(3 \times 5)]=29\div (4 - 8 -15)](https://tex.z-dn.net/?f=%5B4%20%2B%209%20%2B%2016%5D%20%5Cdiv%20%5B4%20-%208%20-%283%20%5Ctimes%20%205%29%5D%3D29%5Cdiv%20%284%20-%208%20-15%29)
![4 + 9 + 16 \div 4 - 8 -(3 \times 5)=-\dfrac{29}{19}](https://tex.z-dn.net/?f=4%20%2B%209%20%2B%2016%20%5Cdiv%20%204%20-%208%20-%283%20%5Ctimes%20%205%29%3D-%5Cdfrac%7B29%7D%7B19%7D)
Case 2:
![[4 + 9 + 16] \div (4 - 8 -3) \times 5=29\div (-7\times 5)](https://tex.z-dn.net/?f=%5B4%20%2B%209%20%2B%2016%5D%20%5Cdiv%20%20%284%20-%208%20-3%29%20%5Ctimes%20%205%3D29%5Cdiv%20%20%28-7%5Ctimes%205%29)
![4 + 9 + 16 \div (4 - 8 -3) \times 5=-\dfrac{29}{35}](https://tex.z-dn.net/?f=4%20%2B%209%20%2B%2016%20%5Cdiv%20%20%284%20-%208%20-3%29%20%5Ctimes%20%205%3D-%5Cdfrac%7B29%7D%7B35%7D)
Case 3:
![4 + 9 + (16 \div 4) - 8 -(3 \times 5)=4+9+4-8-15](https://tex.z-dn.net/?f=4%20%2B%209%20%2B%20%2816%20%5Cdiv%204%29%20-%208%20-%283%20%5Ctimes%20%205%29%3D4%2B9%2B4-8-15)
![4 + 9 + (16 \div 4) - 8 -(3 \times 5)=-6](https://tex.z-dn.net/?f=4%20%2B%209%20%2B%20%2816%20%5Cdiv%204%29%20-%208%20-%283%20%5Ctimes%20%205%29%3D-6)
Many more possibilities are there.
Therefore, there are more than 3 possible solutions.
Answer:
17
Step-by-step explanation:
replace x with 5
3*5+2
next you use pemdas
you multiply before you add
3*5=15
15+2=17
