The video tutorial introduces the concept of modulo and remainder, explaining a four-step process to find remainders without relying on calculators. It provides two examples: 12 modulo 23 and 112 modulo 35, demonstrating the steps of dividing the dividend by the divisor, disregarding the fraction, multiplying the quotient by the divisor, and subtracting the result from the dividend to find the remainder.

Why is it beneficial to understand the modulo operation without using a calculator?

• It is required for all math exams.

• It saves time in calculations.

• It helps in understanding the underlying mathematical operations.

• It is a faster method than using a calculator.

What is the first step in finding the remainder manually?

• Divide the dividend by the divisor.

• Add the dividend and divisor.

• Multiply the dividend by the divisor.

• Subtract the divisor from the dividend.

In the example of 12 modulo 23, what is the quotient after disregarding the fraction?

• 0

• 23

• 12

• 1

What is the remainder when 12 is divided by 23?

• 11

• 12

• 1

• 0

In the second example, what is the quotient when 112 is divided by 35?

• 2

• 4

• 5

• 3

What is the remainder when 112 is divided by 35?

• 5

• 7

• 2

• 10

What is the final step in the four-step process to find the remainder?

• Multiply the quotient by the dividend.

• Divide the new result by the divisor.

• Add the quotient to the dividend.

• Subtract the new result from the dividend.
