Final answer:
To perform the given calculations, you multiply the number by 10, add 10 to the product, divide the sum by 2, and subtract 5 from the quotient. The result is 5.
Step-by-step explanation:
To multiply a number by 10, you simply add a 0 to the end of the number. So, if the number is 1, multiplying it by 10 gives you 10.
To add 10 to the product, you simply add 10 to the result. So, if the product is 10, adding 10 gives you 20.
To divide the sum by 2, you divide the result by 2. So, if the sum is 20, dividing it by 2 gives you 10.
Finally, to subtract 5 from the quotient, you subtract 5 from the result. So, if the quotient is 10, subtracting 5 gives you 5.
Therefore, the result of the given calculations is 5.
