2|2-4|+6 I haven't done this in 3 years and my teacher just threw it at me. I keep getting 2. Please tell me what I'm doing wrong.

See explanation for answer.

Explanation:

2|2−4|+6

= 10

I'm sorry if this isn't correct.

I hope I helped!

Have a lovely day!

This question is easy to solve long as you know the vertical uprights mean to "take the absolute value".

To take the absolute value of a number, simply make it positive if it is a negative number and do nothing if the number is positive.

I don't see an operator between the first '2' and the first '|' so I'm assuming it is multiplication. Is there is an operator there and forgot to put it there, then I'll edit this answer to give the correct answer.

2 * |2 - 4| + 6 # Starting expression

2 * |-2| + 6 # Subtract 4 from 2

2 * 2 + 6 # Absolute value

4 + 6 # Multiplication

10 # Addition

Hope this helps!

if you was gonna solve for a, a is a   < -12
