EXERCISE 1(A)

1. Find the product of each of the following

(+7) * (415) ii) (25) x (16) (ii) (+17) x (+105) (iu) (-21) x (-9)

w (-13) * (-14) (i) (-11) x (315) (vii) (+7) x (-24) (viii) (+23) x (-50)

(ix) (-6) x (+316)

2. Find the quotient:

1) (+52) + (+13) (ii) 1+119) + (+17) (iii) (+243) + (+3) (iv) (-76) + (-19)

(0) (-117) + (-13) (vi) (-294) + (-14) (vii) (+19) + (-1) (viii) (+21) + (-7)

lix) (-76) + (+19) (x) (-217) + (+7) (xi) 0 + (-7)

(xii) 0 (+6)

3. Evaluate

(1) (-1) (-2) * (-3) x (-4) x (-5)

(ii) (-3) x (-5) x (-2) x (-4)

(un) (-1) X (-1) X (-1) x ... 50 times.

(iu) (-1) X (-1) X (-1) x ... 51 times.

(u) (-2) * (-2) x (-2) x ... 9 times.

4. Evaluate

(i) 15625 x (-2) + (-15625) x 98

(ii) 1569 x 887 - 569 x 887

5. The product of two integers is -98. If one of them is 14, find the other.

6. The product of two integers is 144. If one of them is -16, find the other.

7. The product of two integers is -153 If one of them is -17, find the other.

8. Find the value of 132 + 2 x 17 + (-6)] + 15

9. Simplify: (36 + (-9)} = (-24) + 6)
