If a = 3, b = 2 and c = 1,then prove that.
(i) a + b = b + a.
(iii) (a + b) + c = a + (b + c).
(vii) đ– b= (a + b) (a - b).
Summary
the arithmetic.
If x= 1 and y = 1, then prove that (x + y) = x + 2xy + y.
If x= 2 and y = 1,then prove that (x - y) = x - 2xy + y.
Evaluate 2-[2- {2-(2 - 2 - x)}] when x = 1.
If a = 1, b = 3 and c = 1,then evaluate b- 4ac.
(v) a * (b + c) = a × b + axc. (vi) a * (b - c) = axb-​
