Negative Numbers
What are negative numbers?
Negative numbers are the opposite of positive numbers, like said for example, negative 3 (-3) is actually more than negative 20 (-20) !!
What is an Inequality?
An Inequality is a comparison between numbers, values, or expressions.
if x + z = 5 and z is 2, what is x?
What is 3? (it should be obvious y'all)
What type of lines does a coordinate grind with positive and negative numbers have?
What are perpendicular lines? (lines that intersect eachother)
Lets say Annie's house was -10 degrees, if Annie's house got warmer by 21 degrees what temperature is Annie's house?
What is 11? ( The answer is 11 due to the fact negative numbers are below 0, technically the answer is like 21-10 )
What is the unknown variable in X3 =12 ?
The unknown variable is 4, 4 times 3 is 12 which makes X multiplies by three times equal 4, In conclusion since 4x3 is the only thing in 3's multiples that = 12.
What is absolute value?
absolute value is the distance from zero that a number is on the number line.
Which goes first when listing coordinates, x or y?
What is X?
On a number line between -10 to 10 Mia's dog is on 0, if Mia's dog went 5 units to the left, what number would Mia's dog be on?
What is -5? (since 0 is in the middle, any unit to the left would be in the negatives so 5 units to the left would make is -5.)
What would a line under the less than or greater than sign mean?
It means the same thing but also equal to.
(ex: > with a line under = less than or equal to)
What does |-5| equal?
What is 5?
Ray goes to the store which is (6,1) away from his house, if Ray's house was (2,1) what is the distance from Ray's house from the store?
What is (4,0)?
There are 4 trenches that are on a table that show the elevations of the highest and lowest points.
Mariana Trench: -11,033
Puerto Rico Trench: -8,600
Tonga Trench: -10,882
Sunda Trench: -7,725
Which trench has the greatest elevation?
What is 7,725? ( 7,725 is the answer, if we count negative numbers being the opposite of positive numbers, we can use that to determine the greatest number by choosing which one would be the lowest if we were to compare in positive numbers.)
Frye is calculating how much paint she needs so she can paint a wall yellow and purple she happens to have more yellow paint then purple, how many more does she have yellow than purple?
y7 > 20
Anything 3 and above ( 7x2 = 14 and 14 is less than 20)
(SPLATOON REFERENCE!?)
What are two real world uses you can use absolute value for?
distance, magnitude and similar
If a coordinate was (-8,9) where would it be on the grid?
What is the bottom left corner?
A deep-sea fish swims 300 feet down the sea, the fish then swims 1000 more feet. Lets say past the 1000 mark was in the negatives, how deep in the ocean is the fish?
What is -300? (If past 1000 was in the negatives and the fish swam 1000 feet from 300 (300 + 1000 =1300), the answer would be -300 if we took away 1000 and placed a - sign instead
How do you write an Inequality?
using words like "more than" "less than" "at least" "no more than", choose the right variables, and translate to a mathematical inequality using the correct symbols of (<, >, ≤, ≥)
what would represent number n?
A: ()
B: ||
What is B?
(The absolute value of a number n is the distance of the number n from zero)
Where is the 0 on the coordinate grid?
0 In the average coordinate grid is in the middle.
