(-20) × ( 5 - 3) = (-20) × (-2)
Solution:
The requirement of the above question is to prove whether the given statement is true or false.
The given expression is (-20) × ( 5 - 3) = (-20) × (-2).
Now let us put the integer rules and solve the LHS and RHS part.
(-20) × ( 5 - 3) = (-20) × (-2)
-40 ≠ 40
Therefore, using the integer rules, we observed that (-20) × ( 5 - 3) = (-20) × (-2) is a false statement.
✦ Try This: State whether the statement is true or false. (-40) × (-2) = (-40) × (5 - 3)
We can apply integer rules and the order of operations to identify whether (-40) × (-2) = (-40) × (5 - 3) is true or false.
