Arithmetic Properties
Commutative Property
The commuting distance is the same in either direction, from home to work or work to home.
The
Commutative Property tells us that: a + b = b + a or a × b = b × a
Associative Property
To associate with people is to group up with them.
The
Associative Property are about grouping:
(a + b) + c = a + (b + c), or (a
× b)
× c = a
× (b
× c)
Distributive Property
To distribute something is to give it to everyone.
The
Distributive Property “gives” whatever’s outside the parentheses to everything inside: a (b + c)=ab + ac

Mode & Median
Mode
The mode is the value there are the most of.
“MOde” and “MOst” have the same starting 2 letters.
The mode is the Most Occuring Data Entity.
Median
The median splits the data down the middle, like the median strip in a road.

Multiplying Signed Numbers
Analogies can help here.
From sports:
we = pos, win = pos, they = neg, lose = neg, good = pos, bad = neg
we win = good (pos × pos = pos)
we lose = bad (pos × neg = neg)
they win = bad (neg × pos = neg)
they lose = good (neg × neg = pos)
From friendship:
friend = pos, enemy = neg
My
friend's friend is my
friend (pos × pos = pos)
My
friend's enemy is my
enemy (pos × neg = neg)
My
enemy's friend is my
enemy (neg × pos = neg)
My
enemy's enemy is my
friend (neg× neg = pos)
From life:
good = pos, bad = neg
A
good thing happening to a
good person is
good. (pos × pos = pos)
A
good thing happening to a
bad person is
bad. (pos × neg = neg)
A
bad thing happening to a
good person is
bad. (neg × pos = neg)
A
bad thing happening to a
bad person is
good. (neg× neg = pos

Speed, Distance and Time
The following diagram shows the speeddistancetime triangle. Scroll down the page for more examples and solutions on how to use the speeddistancetime triangle.
D = distance traveled
S = Average speed
T = Time taken
You can use the formula triangle in the following way:
If you need to find D, cover up D in the triangle and you get S × T
If you need to find S, cover up S in the triangle and you get
If you need to find T, cover up T in the triangle and you get
