Some more examples of conversions are as follows:
4
1. z = 4x + 2yx + y
Ans. z = 4 * Math.pow(x, 4) + 2 * y * x + y
(a×b)
2. m = a+b

Ans. m = (a * b) / (a + b)
3. s = ut + 1 at 2
2
Ans. s = u * t + (1.0 / 2.0) * a * Math.pow(t,2)
4. f = uv
(u+v)
Ans. f = (u * v) / (u + v)

5. d = (5a + a )
(m + n)
Ans. d = Math.sqrt(5 * a + a * a) / (m + n)
6. p = a + b + 2ab
2
2
Ans. p = a * a + b * b + 2 * a * b
7. y = 2(lb + bh + lh)
Ans. y = 2 * (l * b + b * h + l * h)

Some solved examples:
Arithmetic expressions:
1. int m=15, n; [shows the difference between prefix and postfix]
n = ++m + m;
= 16+16
= 32
n = m++ + m++;
= 15+16
= 31
