(-25) × [6 + 4] is not same as
a. (-25) × 10
b. (-25) × 6 + (-25) × 4
c. (-25) × 6 × 4
d. -250
Solution:
If we solve the given expression (-25) × [6 + 4] using integers properties the final value will be -250. Now, to determine the correct option from the above listed option we need to evaluate all the alternative options.
a) (-25) × 10 = -250
b) (-25) × 6 + (-25) × 4 = -250
c) (-25) × 6 × 4 = -600
d) -250 = -250
Therefore, on simplifying individual options we observe that the option c (-25) × 6 × 4 = -600 is not the same as (-25) × [6 + 4].
✦ Try This: Simplify (-50) × [5 + 7].
Using the integer rules and BODMAS rules we can determine the value of (-50) × [5 + 7]
