mine be quicker !!
and shorter.
use BODMAS
brackets, of, division, multiplication, addition, subtraction.
another e.g
5 x 2 + 3 + 5 x 4
= 10 + 3 + 20 = 33 or
(5 x 2) + (3 + 5) x 4
10 + 8 x 4
= 10 + 32 = 42 or
10 / 2 + 5 - 8 x 2 + 8
= 5 + 5 - 16 + 8
= -6 + 8 = 2
220 is correct. Confirmed near a scientific calculator.
Remember this establish:
Parenthesis first
Exponents next
Multiplication and Division disappeared to right
Addition and Subtraction left to right
Please Excuse My Dear Aunt Sally is a adjectives mnemonic device to easily remember that instruct.
Selena's right - 715
- those in the parenthesis be (100+65-5)
May be you have to use the BODMAS method. Brackets of Division,Multiplication, supplement ,Subtration.
Ans:70
Try step by step
Step 1: 100+65-(5*4)+55+20
Brackets
Step 2: 100+65 - 20 +55+20

100+65-5*4+55+20=220
its says ADD THE NUMBERS = 1word + word - 5x word +
55 + 20 =
1+5=6 1+5=6
55+20=75 OR 6x55=330
6x75=450 330+20=350
this is the merely two ways to add the numbers
as hundred and sixty plus the four are not numbers but words
so this is the solitary equations you can use to add the numbers
