Which set of rational numbers is arranged in ascending order?
Find the sum: (i) 2+4+6+...+200 (ii) 3+11+19+...+803 (iii) (-5)+(-8)+(-11)+...+(-230) (iv) 1+3+5+7+...+199 (v) 7+1012+14+...+84 (vi) 34+32+30+...+10 (vii) 25+28+31+...+100 (viii) 18+1512+13+...+(−4912)
Simplify:(−45×158)+(−13×−97)−(21×2514)
