Study Notes
Order of Operations
- Multiplication is performed before addition
- The expression 3+5imes23 + 5 imes 23+5imes2 is solved by first multiplying 555 by 222
- The expression 7−(3+2)7 - (3 + 2)7−(3+2) is solved by first adding 333 and 222 then subtracting the sum from 777
Equivalent Expressions
- The expression 2(x+3)2(x + 3)2(x+3) is equivalent to distributing the 222
- The expression 2(x+3)2(x + 3)2(x+3) is equivalent to 2x+62x + 62x+6
Substitution
- If x=3x = 3x=3 in the equation y=2x+4y = 2x + 4y=2x+4, the value of yyy is 101010
- Substitute 333 for xxx in the equation y=2x+4y = 2x + 4y=2x+4 then solve for yyy
Distributive Property
- The equation a(b+c)=ab+aca(b + c) = ab + aca(b+c)=ab+ac demonstrates the distributive property
- The distributive property states that multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products
