Answer:
The correct code for this question:
g=float(input("Enter your English test grade:")) #take input from user.
#check conditions
if (g>=100 and g<=90):
print ("A")
#g greater then equal to 100 and less then equal to 90.
if (g>=89 and g<=80):
print("B")
#g greater then equal to 89 and less then equal to 80.
if (g>=79 and g<=70):
print("C")
#g greater then equal to 79 and less then equal to 70.
if (g>=69 and g<=65):
print("D")
#g greater then equal to 69 and less then equal to 69.
if(g<=64):
print("F")
#g less then equal to 64.
else:
print ("Not a grade")
#not a grade or fail.
Explanation:
In this program, we use to take a value from the user and check the value from the various conditions. To check all the condition we use if-else statement and AND operator that check to the range to together.
If -else is a conditional operator. In that, If block is used to check the true part and else part takes false value, and AND is a logical operator that check the two range together

See below
Explanation:
Because sometimes you have to 'carry' a 1 over to the ext column when adding two binary numbers
Example :
1 1 1
<u>+1 1 1 </u> <==== starting in the first R column add 1 + 1 to get 0 and carry 1
then the next column you will add 1 + 1 + 1 = 1 and carry 1 again
then 1 + 1 + 1= 1 and carry 1 again (to column 4) to get
1 1 1 0
