Question

which is Greater?

$1) \: (6 + 7) \times ( - 10)or6 + (7 \times ( - 10)$
$(8 - 9) \times 7or8 - (9 \times 7)$
​

Answer 1

Ans.1 $\red\rightarrow$

i) (6+7)×(-10) = 13×(-10)

= (-130)

ii) 6+{7×(-10)} = 6+(-70)

= (-64)

Hence , 6+{7×(-10)} is greater.

Ans.2 $\orange\rightarrow$

i) (8-9)×7 = (-1)×7

= (-7)

ii) 8-(9×7) = 8-63

= (-7)

Hence , both are same.
