Question

I'm doing my math hw, what does the sign ' mean for sets? Thanks

Answer 1

= equals sign equality 5 = 2+3
≠ not equal sign inequality 5 ≠ 4
> strict inequality greater than 5 > 4
< strict inequality less than 4 < 5
≥ inequality greater than or equal to 5 ≥ 4
≤ inequality less than or equal to 4 ≤ 5
( ) parentheses calculate expression inside first 2 × (3+5) = 16
[ ] brackets calculate expression inside first [(1+2)*(1+5)] = 18
+ plus sign addition 1 + 1 = 2
− minus sign subtraction 2 − 1 = 1
± plus - minus both plus and minus operations 3 ± 5 = 8 and -2
∓ minus - plus both minus and plus operations 3 ∓ 5 = -2 and 8
* asterisk multiplication 2 * 3 = 6
× times sign multiplication 2 × 3 = 6
∙ multiplication dot multiplication 2 ∙ 3 = 6
÷ division sign / obelus division 6 ÷ 2 = 3
/ division slash division 6 / 2 = 3
– horizontal line division / fraction \frac{6}{2}=3
mod modulo remainder calculation 7 mod 2 = 1
. period decimal point, decimal separator 2.56 = 2+56/100
ab power exponent 23 = 8
a^b caret exponent 2 ^ 3 = 8
√a square root
√a · √a = a
√9 = ±3
3√a cube root 3√a · 3√a · 3√a = a 3√8 = 2
4√a fourth root 4√a · 4√a · 4√a · 4√a = a 4√16 = ±2
n√a n-th root (radical) for n=3, n√8 = 2
% percent 1% = 1/100 10% × 30 = 3
‰ per-mille 1‰ = 1/1000 = 0.1% 10‰ × 30 = 0.3
ppm per-million 1ppm = 1/1000000 10ppm × 30 = 0.0003
ppb per-billion 1ppb = 1/1000000000 10ppb × 30 = 3×10-7
ppt per-trillion 1ppt = 10-12 10ppt × 30 = 3×10-10
