ALGEBRAIC EXPRESSIONS

DIVIDING INTEGERS 1. IF THE SIGNS ARE THE SAME THE ANSWER IS POSITIVE 2. IF THE SIGNS ARE DIFFERENT THE ANSWER IS NEGATIVE.

MULTIPLYING MONOMIALS TIMES POLYNOMIALS (DISTRIBUTIVE PROPERTY)

ADDING INTEGERS 1. POS. + POS. = POS. 2. NEG. + NEG. = NEG. 3. POS. + NEG. OR NEG. + POS. SUBTRACT TAKE SIGN OF BIGGER ABSOLUTE VALUE.

MULTIPLICATION EQUATIONS 1. SOLVE FOR X 3. WHAT EVER YOU DO TO ONE SIDE YOU HAVE TO DO TO THE OTHER 2. DIVIDE BY THE NUMBER IN FRONT OF THE VARIABLE.

SUBTRACTING INTEGERS 1. CHANGE THE SUBTRACTION SIGN TO ADDITION

MULT. INTEGERS 1. IF THE SIGNS ARE THE SAME THE ANSWER IS POSITIVE 2. IF THE SIGNS ARE DIFFERENT THE ANSWER IS NEGATIVE.

FACTORING Think Distributive property backwards Work down, Show all steps ax + ay = a(x + y)

FACTORING ax2 + bx + c Think “unfoil” Work down, Show all steps.

Comparative Microbial Genomics group Center for Biological Sequence Analysis The Technical University of Denmark DTU What have we learned from 300 sequenced bacterial genomes? 1. Genetic diversity is greater than we thought. 4. Generally G’s are biased towards the leading strand, but the strand bias of A’s is tax-specific. 2. Very large genomes tend to be GC-rich, whilst small genomes tend to be AT-rich. 3. There are patterns, both locally and globally of AT-richness in bacterial chromosomes.
