is 7+-7=0?

Question

this's a absolute value question

Answer 1

With a problem such as this, it really depends on which number is intended to be within the absolute value brackets. An important thing to remember regardless is that absolute value will always be a positive value since it is, by definition, the distance from 0. 

 

So keeping this in mind, if the first 7 of the problem is in absolute value it will be a positive 7 in the equation. 

 

|7| + -7=0 From there you can determine that the equation will look like: 7-7=0 and solve. 

 

However, if the equation is written in this format your answer will change: 

7+ |-7| = 0  From this you'll find that it will look more like this: 7+7=0  because -7 is a distance of 7 units from 0 and distance will always be positive. 

 

I hope that this points you in the right direction. 

 

Answer 2

Short answer: yes. In this case, the negative overcomes the positive and acts as a subtraction function.
