the fourth digit
(1) 23
3 - 3276 * 2
(11) 8964 | + 99 x 8964
Verity the following:
23 x 7 + 23 (-2)
(0) 23 * 17 + (-2)
((-18) * I(-3) + (-5) = (- 18)
(-3)| + |(-18) (-5)
4. Determine the integer whose product with :-/' is
(ii) - 47
5. Using convenient grouping, evaluate :
(i) (-5) * 19 * (- 60)
(ii) 25 * 31 * (-4)
(iii) 97 * 25 * (- 2) * (- 4)
(iv) (-2) × 4896 × (-5)
6. If a = 3, b = - 2, c = - 1, verify that:
(i) 6x (a + c) = bxa+bxe (ii) bxc * a = a b c = c * a * b
(iii) b c = ( xb
7. If '*' operation be defined as a * b = a × b -- (a + b), evaluate
(ii) (-4) (-6)
(iii) 13 * (-6
(i) 2 * 5
DIVISION OF INTEGERS
Like the whole numbers, division of integers is inverse of multiplication
(1) Dividing 18 by 3 implies that we have to find an integer which when multiplied
Obviously, such an integer is 6.
18.​
