What two plus two?
plz help

4

Step-by-step explanation:

Hello!

We can use simple addition for this one (:.

2 + 2 = 4.

If you want something more to prove a concept here's something I found on qoura:

To give an explanation of the basic addition problem of “2 + 2=4,” suppose we have a person standing on the real number line at the origin or the point corresponding to the integer zero (0). (We know from our study of Algebra that there is a one-to-one correspondence between the set of real numbers and the infinite number of points on a horizontal straight line) Now that the person is standing at zero, the rules are that any movement by the individual to the right is in the positive (+) direction, and that any movement to the left is in the negative (‒) direction.

1.) Let's say that the individual moves from zero to the right 2 units to the point or to the position on the real number line that corresponds to and is labeled positive 2; therefore, we see that positive 2 has an absolute value of 2.

Remember: the absolute value of any real number is its distance from zero (0) on the real number line regardless of direction. For example, │1│= 1, │2│=2, │1/4│= 1/4, │0│= 0, │‒5│= 5, │‒π│= π, and │‒3/2│= 3/2.

2.) Next, the individual decides to move to the right 2 additional units, an increase in absolute value of 2, from the position of positive 2 to the point or position on the real number line that corresponds to and is labeled positive 4; therefore, the total distance of the individual from zero is now 4 units to the right (an absolute value of 4); therefore, in summary, we have:

2 + 2 =│2│+│2│=│2 + 2│=│4│= 4 Since for any two positive real numbers a and b,│a│+│b│=│a + b│= a + b.

So, in conclusion, the addition of two positive integers, in this case the addition of positive 2 to itself (as shown above), is simply the adding together of their absolute values in order to arrive at the resultant sum or total, which in this case is 4.

why do wages differ across industries

step-by-step explanation :

micro economists are concerned with economics on an industry or individual firm basis.

macro economists are concerned with national and international level
