I only got 3 questions wrong out of 14. How come i got a C?

This is my answer:

There was something wrong w/ Mr. Isfeld's Grade Scale, This was the right one:

A	=	90-100	=	4.0	Outstanding
B+	=	87-89	=	3.0
B	=	80-86	=	3.0	Above Average
C+	=	7 7-79	=	2.0
C	=	70-76	=	2.0	Average
D+	=	67-69	=	1.0
D	=	60-66	=	1.0	Lowest Acceptable
F	=	0-59	=	0.0	Failure
I	=	0	=	0.0	Incomplete

Prime Factor

Prime Factor

• Numbers with only 2 factors, 1 and itself.
• Goes into a number with no remainder or a decimal.
  

Divisibility Rules

Rule for 1:

• All whole numbers are divisible by one

e.g:
3÷1=3
111÷1=111

Rule for 2:

• All even numbers are divisible by 2.
• Even numbers end in 0, 2, 4, 6, and 8.
• Odd numbers end in 1, 3, 5, 7, and 9.

Rule for 4:

• All numbers that are divisible by 2 twice.

e.g:
16÷2=8÷2=4
16 is divisible by 4.

Rule for 8:

• All whole numbers divisible by 2 thrice.

e.g:
24÷2=12÷2=6÷2=3
24 is divisible by 8.

Rule for 5:

• All numbers ending in 5 or 0.

e.g: 5,10,15,20........
