To solve 43 times 45 using the front-end estimation method, follow these steps:
1. Identify the place value of the front-end digit. In this case, it is 4, which represents the tens place.
2. Ignore all other digits after the front-end digit, making any subsequent digits zero. So 43 becomes 40.
3. Multiply the front-end digit by the other number. In this case, 45 times 4 equals 180.
Therefore, by using the front-end approximation method, 43 times 45 is approximately equal to 180.
