Times, x, and multiply
The expression (2 \times 3 \times 5) equals (30). To break it down, first multiply (2) by (3) to get (6), and then multiply (6) by (5) to arrive at the final result of (30).
Multiply 3 times 25 mentally (the answer is 75), and then adding three zeroes will give the total of 75,000.
