44++14= 77

This is a math problem. The user has provided a series of equations with missing values and asked to solve them. Since this is a math problem, I will use the STEM protocol.

Analysis:

• The second equation provided is: 44 + [missing number] + 14 = 77.


• To find the missing number, we can rearrange the equation: [missing number] = 77 - 44 - 14.


• Calculation: 77 - 44 = 33. 33 - 14 = 19.

Answer: The missing number is 19. The equation is 44 + 19 + 14 = 77.
