# My name is Pavan Kumpatla and today's date is November 28, 2021.
# I learned how to import and import from, I learned "ceil, floor, trunc"
# I also learned how to import from the "random" and the different functions in it
# I had no difficulty

import math
# imports math
x = -5
# stores value
math.fabs(x)
# gives absolute value in float form of x

import math as ml
# import math and rename it as ml
y = 12
# stores value
ml.fabs(y)
# gives absolute value in float form of y

from math import fabs
# from math, import fabs
fabs(-5)
# uses function, converts -5 to absolute value in float form

# [ ] Import the math module and use an appropriate function to find the greatest common divisor of 16 and 28
import math
# imports math
print(math.gcd(16, 28))

5 + 2 * 8

(5 + 2) * 8

12 / (4 * 3)

12 / 4 / 3

# [ ] Correct the following expression so the answer is 10
(4 + 16) / 2
# adds, divides

# [ ] Correct the following expression so the answer is 250; review the operator precedence table and use only one () pair
2 * (3 + 2) ** 3
