Here is one way I learned from teacher take 267 and ÷ by 3 and there are three part and if you do it right you might have a left over so and take one of those three ÷ and see how much you have left and × it by 2
119.32 = 2 x 3.14 x r
r = 19cm
area = 3.14 x 19^2
= 1133.54cm2
Y=4x-14 to find the slope you need to do
rise/run and to find b you need to see where the line crosses the y axis
Acute
Angle ∠ A = α = 25.385° = 25°23'6″ = 0.443 rad
Angle ∠ B = β = 73.004° = 73°14″ = 1.274 rad
Angle ∠ C = γ = 81.611° = 81°36'41″ = 1.424 rad
Decimal: It’s easier to work with the numbers You can add, subtract, multiply and divide in your head (for the most part) instead of having to find common denominators and things like that.
Fraction: You can put repeating values in fraction form to represent them in a simpler way, as opposed to having to put the line over the repeating digits if it were in decimal form.
Power: Powers are just condensed forms of repeated multiplication, so they save space/time and you can use certain properties with some powers that allow you to multiply and divide them instantly.
Scientific notation: This is good when you’re dealing with numbers that have a lot of digits/place value. That can become confusing, so scientific notation is a way we can represent these numbers clearly and more condensed (takes less space/time).
