Question

How many additions would you need to perform for calculating the total cost if I had bought n items? Give your answer in terms of n, as an expression in n.​

Answer 1

Answer:

The Answer Is ( n - 1 ) .

Explanation:

Let, We have 3 items named a,b,c respectively.

Now, for calculating the total cost of the items we have to add the cost of the items .

cost of a + cost of b + cost of c = total cost

Number of additions = ( Number of items - 1 )

=> Number of additions = 3 - 1

=> Number of additions = 2

Similarly if we have ' n ' items,

then number of additions will be ( n - 1 ) .

Answer 2

There will be n number of additions or calculating the total cost of n items.

• The act of combining two or more items is known as addition. The process of computing the sum of two or more numbers in mathematics is called addition. It is a fundamental mathematical procedure that is frequently used in daily life. When we work with money, figure out our food bills, or figure out the time, we frequently employ addition.
• The statement that demonstrates an addition fact is known as the addition formula and is written as addend + addend = sum.

Here, according to the given information, we are given that,

We need to calculate the total cost of n items that were bought.

Now, in order to do so we need to add up each cost of n items. This means that there has to be additions in the form of n number of additions.

Hence, there will be n number of additions or calculating the total cost of n items.
