the straight lines surrounding the numbers is known as "absolute values" --- what that means is you are taking the value of the number and disregarding any sign...
therefore,
4 + 3 = 7

When you see whose lines with a number in between that means you make the number positive so it would be 4+3 because the -3 becomes positive and the 4 stays positive so the answer would b e 4+3=7
\4\ + \-3/ =
4 + 3 = 7

The |4| symbol means absolute value of 4, which basically means to change it to a positive number. Since 4 is already positive, there is no change in sign required. However, |-3| becomes 3
So,
|4| + |-3| = 4 + 3 = 7

Hey there!
Recall that |x|=x and |-x|=x. This is the definition of an absolute value. We can use this definition to solve the problem.
|4|+|-3| -->
4+3 -->
7
So the answer is 7.
Hope it helps!

[ ] means absoulte value and absoulte value is a=the amount the number is from zero so [4] is 4 and [-3] is 3 so you come to 4+3 which is 7 first you find the absoulte value then add thats it

|x| = |-x| = x
So |4| + |-3| = 4+3 =7
