Math question: How many times does the digit 2 appear in the number 2218?

The digit 2 appears twice in the number 2218. To find this, we can break down the number into its place values. The digit 2 appears once as the thousands place value and once as the units place value. Therefore, it occurs two times in total.

What is the sum of the digits of the number 2218?

The sum of the digits of 2218 is 2 + 2 + 1 + 8 = 13.

Math question: What is the sum of all even numbers from 2 to 2218?

To find the sum of even numbers from 2 to 2218, one can apply the formula for the sum of an arithmetic sequence. The first term (a) is 2, the last term (l) is 2218, and the common difference (d) is 2, since we are adding even numbers. The formula for the sum of an arithmetic sequence is S = (n/2)(a + l), where n is the number of terms. To find n, we can use the formula n = (l - a) / d + 1. Plugging in the values, we get n = (2218 - 2) / 2 + 1 = 1110. Therefore, the sum of all even numbers from 2 to 2218 is S = (1110/2)(2 + 2218) = 1,110,555.
