ADDITION:
Positive:
(+a) + (+b) = (+c)
Negative:
(-a) + (-b) = (-c) (add and give -ve sign)
-ve & +ve :
(-a) + (+b) = (±c) (The number which is greater that numbers sign should be given)
SUBTRACTION:
Positive:
(+a) - (+b) = (+c) (a > b)
(+a) - (+b) = (-c) (a < b)
Negative:
(-a) - (-b) = (-c) (a > b)
(-a) - (-b) = (+c) (a < b)
-ve & +ve:
(-a) - (+b) = (-c)
(+a) - (-b) = (+c) (Add and give positive sign)
MULTIPLICATION:
(+a) × (+b) = (+c)
(-a) × (+b) = (-c)
(+a) × (-b) = (-c)
(-a) × (-b) = (+c)
DIVISION:
(+a) ÷ (+b) = (+c)
(-a) ÷ (+b) = (-c)
(+a) ÷ (-b) = (-c)
(-a) ÷ (-b) = (+c)
