Example
5 = 2+3
5 ≠ 4
5 > 4
4 < 5
5 ≥ 4
4 ≤ 5
2 × (3+5) = 16
[(1+2)*(1+5)] = 18
1 + 1 = 2
2 − 1 = 1
3 ± 5 = 8 and -2
3 ∓ 5 = -2 and 8
2 * 3 = 6
2 × 3 = 6
2 ∙ 3 = 6
6 ÷ 2 = 3
6 / 2 = 3
√a · √a = a
7 mod 2 = 1
2.56 = 2+56/100
23 = 8
2 ^ 3 = 8
√9 = ±3
3√8 = 2
4√16 = ±2
for n=3, n√8 = 2
10% × 30 = 3
10‰ × 30 = 0.3
10ppm × 30 = 0.0003
10ppb × 30 = 3×10-7
10ppb × 30 = 3×10-10
1% = 1/100
1‰ = 1/1000 = 0.1%
1ppm = 1/1000000
1ppb = 1/1000000000
1ppb = 10-12
