Is the there a way to multiply each NSNumber contained in the array by 10? Here is what I have so far:

NSMutableArray *vertex = [NSMutableArray arrayWithCapacity:3];

[vertex addObject:[NSNumber numberWithFloat:1.0]]; 
[vertex addObject:[NSNumber numberWithFloat:2.0]];
[vertex addObject:[NSNumber numberWithFloat:3.0]];

[vertex makeObjectsPerformSelector:@selector(doSomethingToObject:)];

I am not sure what selector to use to do this, please help!
