Math question: If a number is reduced by 50% and then increased by 30%, what is the final result?

To find the final result, we calculate the reduction and increase separately. First, reducing 2638 by 50% gives us (1 - 0.50) * 2638 = 1319. Then, increasing this reduced amount by 30% yields (1 + 0.30) * 1319 = 1715.7. Hence, the final result after reduction and increase is approximately 1715.7.

Math question: What is the remainder when 2638 is divided by 7?

To find the remainder when 2638 is divided by 7, we can use the mod function. Taking the mod of 2638 and 7 gives us the answer. So, 2638 mod 7 = 1. Hence, the remainder when 2638 is divided by 7 is 1.

Math Question: What is the sum of the digits in the number 2638?

To find the sum of the digits in the number 2638, we add the individual digits together. 2 + 6 + 3 + 8 = 19. So, the sum of the digits in 2638 is 19.
