questions are things like what is the prime factorization of 120 and how do you add 2 3/4 + 5 4/5? I used to know this but it's been so long ago. If I just had a little help I wouldn't have to take a whole class on this for no real credit. Can anybody help me?

for prime factorisation first go on dividing by 2 to see how many factors of 2 you have,the by 3 and then by 5,and 7 and 11,and13 etc till you do not have any factor left other than 1.e.g.
120/2=60/2=30/2=15/3=5/5=1 and so 120=2*2*2*3*5 which can also be written as 2^3*3*5
for adding mixed nos.,
first convert the mixed numbers into vulgar fractions
then reduce both to a common denominator,say the LCM
when the denominators are the same the rule is to just add up the numerator
e.g. 2 3/4=11/4 5 4/5=29/5 LCM of the Dr's.is 20
11/4=55/20 and 24/5=116/20 adding up =>171/20 expressing as a mixed number the answer is 8 11/20
any other types of sums ask and it shall be done for you.we are here to help you and share our knowledge

Here are some tricks that will help you in college.

Sit the exam and try your best.

But get a doctor's note, ideally now but possibly afterwards. Get the doc to say you are suffering from some illness or mental health problem, even if it's just 'stress'.

Also say you are having difficult life circumstances.

Submit this to your school/college and they will probably give you a 'pass' rating.

You can't use this trick all the time though unless you have or pretend to have a disability.
