These three equality constraints except one argument which can be any of the following:

#### A UIView
if you want view.left to be greater than or equal to label.left
instead of :
```obj-c
make.left.greaterThanOrEqual(label.left);
```
#### 2. UIView
you can simply write :
if you want view.left to be greater than or equal to label.left :
```obj-c
//these two constraints are exactly the same
make.left.greaterThanOrEqual(label);
make.left.greaterThanOrEqual(label.left);

### Learn to prioritize

Priorities are can be tacked on to the end of a constraint chain like so:
```obj-c
make.left.greaterThanOrEqual(label.left).with.priorityLow();
make.left.greaterThanOrEqualTo(label.left).with.priorityLow();
make.top.equal(label.top).with.priority(600);
```
