Some simple operations are possible on vectors .
```
      VBIAS     : Y(i) = a + X(i)
      VSCALE    : Y(i) = a * X(i)
      VADD      : Z(i) = X(i) + Y(i)
      VMULTIPLY : Z(i) = Z(i) * Y(i)
      VSUBSTRACT: Z(i) = X(i) - Y(i)
      VDIVIDE   : Z(i) = X(i) / Y(i)
```
In these operations the resulting vectors are created automatically. Note that for operations with mathematical functions like SQRT or trigonometric functions etc... , SIGMA must be used (we will see examples later).
