in the numeral 1 992, the thousand digit is increased by 7 and the tens digit is decreased by 4. what is the new number formed?
really ?
To find the new number formed after increasing the thousand digit by 7 and decreasing the tens digit by 4, we need to break down the original number, 1992.
The original number, 1992, can be expressed as:
(1 x 1000) + (9 x 100) + (9 x 10) + (2 x 1)
Now let's modify the original number based on the given condition:
1. Increase the thousand digit by 7:
Thousand digit: 1 + 7 = 8
2. Decrease the tens digit by 4:
Tens digit: 9 - 4 = 5
Now we have:
Updated number = (8 x 1000) + (9 x 100) + (5 x 10) + (2 x 1)
Simplifying the above expression, we find the new number formed:
New number = 8000 + 900 + 50 + 2 = 8952
Therefore, the new number formed after increasing the thousand digit by 7 and decreasing the tens digit by 4 is 8952.
