Four operations
Addition: putting together
Identity property:
A + O = A
Communitive Property (Order Property): when adding two numbers together the order doesn't matter.
a+b=b+a
3+4 = 4+3
Associative Property (Grouping): when adding numbers the grouping does not matter.
(a+b)+c= a+(b+c)
Subtraction (Take Away)
Comparison
Missing Addend
________________________________________________________________
Multiplication (Repeated Addition)
2+2+2 = 3x2
Identity: when a number is multiplied by one it will stay the same
Ax1 = A, 1x1 = 1
commutative property: when you multiply two numbers together the order doesn't matter.
A,B
AxB = BxA
3x7 = 7x3
associative property: when multiplying numbers the grouping does not matter
(a*b)xc=ax(b*c)
Zero Property
anything multiplied by zero will equal zero
Ax0 = 0
3x0 = 0
Array
How many numbers will go into a group
Distributive property
A x (B+C) = (AxB) + (AxC)
went over homework number 2 and did mind map
went over base numbers
Base 10:
ones 10^0
tens 10^1
hundreds 10^2
thousands 10^3
Base 5
ones 5^0
fives 5^1
25s 5 ^2
125s 5^3
Base 3
ones 3^0
threes 3^1
nines 3^2
27s ^5
Numberation systems
Base 10 or a decimal systems
Expanded notation
373
300 + 70 + 2
3x100 = 7x10 + 2x1
digits used: 0,1,2,3,4,5,6,7,8,9
Base-10/Decimal
used in schools and daily life
consistent one to ten relationship between the digits in base-10
EX: ten units make a ten, Ten tens make 100
Went over problem-solving again
Understand the problem
Devise a plan (trial and error, make a table, picture, diagram)
Carry out the plan ( be patient)
Look back and reflect (Does It make sense)
Solved problems that required different combinations
Went over the handshake problem
Went over the problem with stamps
Went over the problem with basketball teams
01/13/2021
Went over the syllabus and introductions
