The digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 are substituted by a, b, c, d, e, f, h, i, j. Then find the value of (c+j)×b+j÷d−a+e
Find eachof the following products:
(a) 3 ×(− 1) (b) (− 1) ×225
(c) (−21) × (− 30) (d) (−316) × (− 1)
(e) (−15) × 0 ×(−18) (f) (− 12) ×(− 11) × (10)
(g) 9 ×(− 3) × (−6) (h) (− 18) × (−5) × (− 4)
(i) (−1) × (−2) ×(− 3) × 4
(j) (−3) × (− 6) ×(− 2) × (− 1)
