Scientific Notation Addition Quiz

The video tutorial from MooMooMath and Science explains how to add numbers in scientific notation. It covers the basic rule that exponents must be the same for addition, demonstrates how to adjust exponents when they differ, and provides examples of both correct and incorrect scientific notation. The tutorial also includes a complex example requiring multiple adjustments and emphasizes the importance of keeping the first number between 0 and 10.

What is the first rule when adding numbers in scientific notation?

• The exponents must be different.

• The exponents must be the same.

• The base numbers must be equal.

• The base numbers must be different.

What should you do if the first number in scientific notation is not between 0 and 10?

• Add 2 to the exponent.

• Subtract 2 from the exponent.

• Move the decimal to the right.

• Move the decimal to the left.

How do you handle different exponents when adding in scientific notation?

• Add the exponents together.

• Make the numbers equal by adjusting the exponents.

• Ignore the exponents and add directly.

• Subtract the smaller exponent from the larger one.

What happens to the exponent when the decimal is moved to the left?

• The exponent decreases.

• The exponent remains the same.

• The exponent is divided by 2.

• The exponent increases.

In the example where the number is 34 times 10 to the third, what adjustment is made?

• The number is increased to 340.

• The number is decreased to 3.4.

• The exponent is decreased by 1.

• The exponent is increased by 2.

What is the result of moving the decimal two places to the left in the final example?

• The number becomes larger.

• The exponent increases by 2.

• The number becomes smaller.

• The exponent decreases by 2.

Why is it necessary to adjust the exponent when the decimal is moved?

• To keep the number in standard form.

• To change the base of the number.

• To make the number smaller.

• To make the number larger.

What is the final result of the last example in the video?

• 5.781 times 10 to the third

• 5.781 times 10 to the fifth

• 57.81 times 10 to the fifth

• 57.81 times 10 to the third

What is the effect of moving the decimal to the right on the exponent?

• The exponent increases.

• The exponent decreases.

• The exponent is multiplied by 2.

• The exponent remains unchanged.

What is the key takeaway from the video regarding kindness?

• Kindness subtracts kindness.

• Kindness is irrelevant to math.

• Kindness multiplies kindness.

• Kindness divides kindness.
