This is relatively basic and uses the following priorities: Parenthesis Exponent Multiply / Divide Add / Subtract or PEMDAS. So something to simplify may be: 3^3x2+4=? Note that x is a multiplication sign 27x2+4 no parenthesis so exponents first 52+4 multiplication...

When solving inequalities, the sign is flipped when dividing theequation. In this one, though, it's not necessary. S+9>24 make sure you're going in the right direction. In this case, the inequality is greater than a numerical value. When graphing, make sure of 2 things: 1. The line is...

Angles have a long and diverse history. Their origin is deeply roted in metaphysics and extends far back beyond organic cognitive thinking or our planetary history. From the start of solar orbit, planets acted as satellites rotated around planets in a variable orbit measured in degrees. The measure...

Remember to keep with order of operations! Multiply before addition or subtraction. 4x4+4x4+4-4x4 multiply all first 16+16+4-16 "cheat" 16-16=0 16+4=20

Good question. Think of this as a general heuristic or a rule of thumb that works only when the first term usually x^2 is 1. I'll use some examples: X^2+5x+6 both are positive so the answer will have two positive signs X^2-5x+6 both are negative.  X^2-5x-6 this with...

X+6=3(5-x) distributive property X+6=15-3x add 3x and subtract 6 from either side 4x=9 divide by 4 to get 1x X=(9/4) or 2.25

When converting volume to weight, one needs to find the density which will give a conversion factor. For example, the density of water is 1. So, 30,220 x 1(g/ml) = 30,220g. however, if you're working with something like salt: density NaCl=2.165(g/ml), so 38,220mL x 2.165(g/ml) =82,746 If...

7e=f 7(3)=f 21=f plug in, multiply, solve

Interpolation and extrapolation can be used in more forms than linear algebra. In a realistic sense, one could interpolate what happened to the price of oil between the dates of 1975 and 1978 given that data can be obtained for reference. Because of this, interpolation is relatively safe. However...
