Degrees, Minutes, and Seconds Operations

This video tutorial explains how to add and subtract values in degrees, minutes, and seconds. It covers the process of adding and converting seconds and minutes when they exceed 60, as well as borrowing techniques for subtraction. The tutorial also provides examples using TI calculators and emphasizes the importance of conversion to ensure accurate results.

What is the first step when adding values in degrees, minutes, and seconds?

• Start with the minutes

• Start with the degrees

• Start with the seconds

• Start with the largest value

If you have 85 seconds, how should it be converted?

• 1 minute and 25 seconds

• 2 minutes and 5 seconds

• 1 minute and 15 seconds

• 85 seconds is fine as it is

What should you do if your minutes value exceeds 60?

• Subtract 60 from the minutes

• Convert 60 minutes into 60 seconds

• Convert 60 minutes into one degree

• Leave it as it is

When subtracting, what should you do if the seconds in the minuend are less than the subtrahend?

• Borrow a minute from the minuend

• Add a degree to the minuend

• Add a minute to the minuend

• Subtract directly

How many seconds are in one minute?

• 120 seconds

• 90 seconds

• 60 seconds

• 30 seconds

What is the result of subtracting 46 degrees, 22 minutes, and 45 seconds from 85 degrees, 15 minutes, and 37 seconds?

• 37 degrees, 51 minutes, 51 seconds

• 40 degrees, 54 minutes, 54 seconds

• 39 degrees, 53 minutes, 53 seconds

• 38 degrees, 52 minutes, 52 seconds

What should you do if your seconds value is greater than 60 when adding?

• Leave it as it is

• Convert 60 seconds into one minute

• Convert 60 seconds into one degree

• Subtract 60 from the seconds

What is the importance of borrowing in subtraction of degrees, minutes, and seconds?

• To make the minuend smaller

• To make the minuend larger

• To make the subtrahend smaller

• To make the subtrahend larger

What should you do if your minutes value is greater than 60 when adding?

• Subtract 60 from the minutes

• Convert 60 minutes into one degree

• Leave it as it is

• Convert 60 minutes into 60 seconds

What is the final step after adding or subtracting degrees, minutes, and seconds?

• Subtract all values again

• Add all values together again

• Check if any value exceeds 60 and convert if necessary

• Leave the values as they are
