# Numbers and Math in Python

### Numbers and Math

This exercise has lots of math symbols. Here are the names:

 The symbol The Name The Work + plus Addition - minus Subtraction * asterisk Multiplication % percent Division < less-than compare > greater-than compare <= less-than equal-to compare >= greater-than equal-to compare

Let’s write a piece of code and check the outputs,

# normal maths
print("Apples", 3+4+2/3)   # fist-case
print("Banana", 10*6+2-3)  # second-case

# comparison
print(3 + 9 < 9 - 8)       # third-case

# modulus action
print(15 % 4)              # fourth-case


So, run the code now and try to understand the output

OUTPUT :

Apples 7.666666666666667
Banana 59
False
3

##### observations
• In the first case & second case, the print() function has one string and one mathematical expression separated by comma, where the mathematical expression is solved by the normal BODMAS rule.
• In the third case, we had a comparison and it returns Boolean datatype. Which means binary (0 & 1) . True is treated as 1 and False is treated as 0.
• In the fourth case we are dealing with the % operator which simply means modulus but not percent here. In simpler words a % b means, the reminder obtained when a is divided by b. For example here 15 is divided by 4 and the reminder obtained is 3.

Q - You are given a list of marks(out of 100) for a student. Your aim is to print the corresponding percentage of the student.

​ Mathematics - 50

​ Physics - 85

​ Social Science - 60

​ Also print the total aggregate percentage.
