monotony
w If both members of inequality is compounded by a single number, you get another inequality in the same direction.
w If you add two inequalities limb from limb in the same direction, you get another inequality in the same direction as the previous. Definition
or Subtraction subtraction is the inverse function of the sum. The difference between a natural number a and another natural number b is equal to a number r, which added ab gives the number a.
From the above definition we can say that the subtraction of two natural numbers is a feature that some ordered pairs of natural numbers correspond makes another natural number called difference. The subtraction is only defined for ordered pairs in which: To view the graphs enter this page by clicking here
property of monotony in the sum:
8> 7
if you add the same on both sides of inequality does not change
eg: 8 + A> 7 + A
If you subtract that also happens:
8-1> 7-1
is "uniformity" of the sum.
also works with the equalities:
eg: X +10 = 4
subtract 10 to both sides ... X +10 -10 = 4-10
mean ... X = -6 (q is in use in clearing equations)
