(-1) × (-2) × (-3) = 1 × 2 × 3

Solution:

The requirement of the above question is to prove whether the given statement is true or false.

The given expression is (-1) × (-2) × (-3) = 1 × 2 × 3.

Now let us put the integer rules and solve the LHS and RHS part.

(-1) × (-2) × (-3) ≠ 1 × 2 × 3

-6 ≠ 6

Therefore, using the integer rules, we observed that (-1) × (-2) × (-3) = 1 × 2 × 3 is a false statement.

✦ Try This: State whether the statement is true or false.(-1) × (-8) × (-9) = 1 × 8 × 9.

We can apply integer rules and the order of operations to identify whether (-1) × (-8) × (-9) = 1 × 8 × 9 is a false or true.
