Lesson 11: Comparing negative numbers

# Ordering negative numbers

Ordering negative numbers can be tricky, but understanding their values is essential. Smaller negative numbers are further from zero, making them less than larger ones. Visualizing them on a number line helps clarify their positions, with the least number on the left and the greatest on the right. Think of owing money or cold temperatures for real-life examples.

• Can fractions be negative?
• Yes, fractions can be negative. Follow the same logic that Sal uses in this video to help in ordering them.
• Is there a negative 1/2?
• It can be a negative number if we either put the minus sign in front of 1 or 2.
• Is there an end to the number line? How long is the number line anyways? - Mia:)
• The number line never ends. It continues forever. You will see it describe as continuing to positive infinity (on the right) and negative infinity (to the left).
• Can mixed numbers be negative? How would you place them on the number line?
• Yes. A mixed number can be negative.It's the same as a reguler number just with a little extra.
So we'll say you had the fraction -1 1/2 and you had to put it on a number line, it would look like this....
-2_____X_____-1_________0________1
(X being the 1 1/2) If I made this confusing please tell me. I Hope this will help.
• this is way to easy, I am getting full on everything, but if anyone needs help, come to me!
• why is -7 higher than -40
• Any number further to the right on a number line is larger. -40 is left of -7 on a number line, so the -7 is larger than the -40
Another way to think about it... which is warmer? -7 degrees or -40 degrees? -7 is warmer. It is less negative than -40.
• For subtracting negative numbers, does the number increase or decrease?
• When you subtract a negative number, it becomes addition.
• Can negative numbers be divided?
• Yep! it works just like dividing positive numbers. Remember that multiplying or dividing a negative number by another negative number makes a positive number. For example:
-4/2 = -2
but
-4/-2 = 2
