642 x 257 equals 165,294. To calculate this, you would multiply the units digits (2 x 7 = 14), carry over the 1, then calculate the tens digits (2 x 5 = 10, plus the carried over 1 = 11), carry over the 1 again, and finally calculate the hundreds digits (2 x 2 = 4, plus the carried over 1 = 5). This process is repeated for each place value to arrive at the final product.
