Adding and Understanding Scientific Notation

The video tutorial from MooMooMath explains how to add numbers using scientific notation. It emphasizes the importance of having the same base and power for the numbers being added. If the powers differ, adjustments to the coefficients are necessary. The video provides several examples to illustrate these concepts, showing how to adjust coefficients and exponents to maintain correct scientific notation. The tutorial concludes with a summary of the key steps involved in adding numbers in scientific notation.

What is the main topic discussed in the video?

• Dividing with scientific notation

• Subtracting with scientific notation

• Adding with scientific notation

• Multiplying with scientific notation

What must be the same when adding numbers in scientific notation?

• The units

• The decimal places

• The base numbers and powers

• The coefficients

In the first example, what is the result of adding 2 and 4 in scientific notation?

• 12 times 10 to the 3rd

• 10 times 10 to the 3rd

• 8 times 10 to the 3rd

• 6 times 10 to the 3rd

What adjustment is needed if the sum of coefficients is not between 1 and 10?

• Add more coefficients

• Change the base number

• Increase the exponent

• Decrease the exponent

How do you adjust the exponent when the decimal is moved to the left?

• Keep the exponent the same

• Double the exponent

• Increase the exponent by one

• Decrease the exponent by one

In the example with different exponents, what is the result of adding 3 and 4?

• 7 times 10 to the 4th

• 7 times 10 to the 3rd

• 4.3 times 10 to the 4th

• 3.3 times 10 to the 4th

What happens to the number when the exponent is increased?

• The number becomes larger

• The number becomes smaller

• The number stays the same

• The number doubles

In the final example, what is the result of adding 4.5 and 2?

• 6.5 times 10 to the 3rd

• 6.5 times 10 to the 2nd

• 6.5 times 10 to the 4th

• 6.5 times 10 to the 5th

What is the relationship between the coefficient and the exponent?

• Inverse relationship

• Direct relationship

• No relationship

• Exponential relationship
