Simplify:
(1) 2+(−4)−(+3)
(2) −5+4−(−2)
(3) 10+(−5)−(−4)
(4) 12−(+6)+(−3)
(5) −15+(−4)−(+3)
Find and correct the errors in the following mathematical statement. Substituting x = −3 in
(a) x2 + 5x + 4 gives (−3)2 + 5 (−3) + 4 = 9 + 2 + 4 = 15
(b) x2 − 5x + 4 gives (−3)2 − 5 (−3) + 4 = 9 − 15 + 4 = −2
(c) x2 + 5x gives (−3)2 + 5 (−3) = −9 − 15 = −24
If A (4, -3) & B (-8, 6) have respective coordinates
