Diyoshana, Hemant and Rupesh got different answers for this problem: {-10-3(10÷2)}-4. Diyoshana's answer was 1, Hemant's answer was -29, and Rupesh's answer was 21

a). Which student had the correct answer?
b). Show and explain how other two students got their answers. What errors did they make?

My opinion on this:
this is a way to long question

I'm giving 20 points for this​

a)hemant is correct

b) they didn't solve this according to BoDMAS so they got wrong answer

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
