Evaluate each expression |2| + |-13|​

answer: 15

step-by-step explanation:

2 + 13

20 ÷ (5 × 2 - 6) + 8=20:(10-6)+8=20:4+6=5+6=11

(20 ÷ 5) × 2 – 6 + 8=4*2-6+8=8-6+8=2+8=10

20 ÷ (5 × 2) – 6 + 8=20:10-6+8=2-6+8=-4+8=4

(20 ÷ 5) × (2 – 6) + 8=4*(-4)+8=-16+8=-8

The code with explanatory comments are given in Python below

Explanation:

#2.22

s = "Lionel Pogba"   #string s with names having LP as initials

names = s.split()  #splits the string into individual characters

initial = ""  #we are initialising the initials as an empty string

for i in names:

   initial += i[0]  #making the initials of the string

print(initial)

#2.23

l = [3, 7, -2, 12]  

range = (max(l) - min(l))  #declare and initialise variable range for the range

print(range) #output of the range

#2.24

l1 = [3, 7, 17, -2, 12]

#(a)

midIndex = int(len(l1)/2)  #evaluates half the length of the list

#which corresponds to the middle index of the list

print(midIndex)

#(b)

print(l1[midIndex])  #assigns the value of the middle index of the list

#corresponding to the middle element

#(c)

l1.sort(reverse=True) #reverses the elements of the list to descending order

print(l1)

#(d)

firstValue = l1[0]  #firstValue variable representing the first element

l1 = l1[1:] + [firstValue] #assigning the location to the last position

print(l1)
