LCM and GCF
What does LCM stand for?
least common multiple
What are the steps in the order of operations?
Parenthese, exponents, multiplication, division, addition, subtraction
Simplify:
5x +3y - 2x +4y
3x +7y
What is the correct way to write an ordered pair?
(x,y)
What is the base of the exponent?
The number that this being repeated.
What does GCF stand for?
Greatest common factor
True or False: You can divide before you multiply during PEMDAS
true: if division comes first in the order the equation is written, you can divide first
Simplify:
3y + 7 - 2y + y - x + 1
2y + 8 -x
Which axis is vertical on a coordinate plane?
y - axis
What does the exponent represent?
The number of times you multiply the base by itself.
What is the LMC of 27 and 33?
LCM= 3
Solve: 4-2 (5 x 10) -2
98
Simplify:
x+(x+x)(x+x)
5x squared
Which axis is horizontal on a coordinate plane?
x- axis
If a base is squared, what does that mean?
The base is being multiplied by itself once
(the base repeats twice)
What is the GCF of 56 and 64?
GCF= 8
What is the third step in this equation?
5 x 4- (10 +5 ) + 2
Simplify:
6x +7(y)- x(2) +7
8x +7y +7
Which quadrant is the ordered pair ( -3, -2) found?
Quadrant 3
What does cubed mean?
Something to the power of three
The base is being multiplied by itself twice
The base repeats 3 times
Can you have a GCF or LCM of 1?
Yes, if there are no other factors that the pair of numbers have in common
Solve:
five times two to the third power minus 3
37
Why do we combine like terms?
To simplify the expression.
Which quadrant is the ordered pair ( 6, -7) found?
Quadrant 4
Solve:
What is five to the power of 4?
625
