27-12+4. Please read description. Description:
This is kinda embarrassing to ask...but I keep getting different answers!
Some calculators say it's 19, but when I work it out, I can only get 11!.

So I add 12+4 to get 16.
Then I subtract from 27 and get ll.
Please help and explain what I'm doing wrong please help. I use PEMDAS btw

OKAY! LISTEN THIS CHANGED MATH FOREVER!

Step-by-step explanation:

Use MathPapa it is AMAZING! it will also give you a step by step if you want, and it is Free! (The answer is 19 btw)

27−12+4

=15+4

=19

When using Pemdas you do addition or subtraction in the order that it comes (so which ever is first). Same with multiplication and Division

step-by-step explanation:

i dont really.know

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
