Item formats

### Active Math Java offers three item layouts:

**Right hand side:**This is the conventional layout with the answer on the right hand side.**Middle:**This is the first algebraic format in the form a + x = b, where a and b are given and the student has to solve for x. Some people call this a number puzzle.**Left hand side:**This is the second algebraic format in the form x + a = b, where a and b are given and the student has to solve for x. Some people call this a number puzzle.

### Active Math Java offers four numeric operations:

**Addition****Subtraction****Multiplication****Division**

### Active Math Java offers seven orders of magnitude:

**Whole integers:**These are traditional primary school sums, differences, products and quotients of whole numbers.**Whole tens:**For items in the conventional form a + b = x, where a and b are given and the student has to solve for x, both a and b are raised by a single power of 10 for addition and subtraction, but only a is raised by a single power of 10 for multiplication and division.**Whole hundreds:**For items in the conventional form a + b = x, where a and b are given and the student has to solve for x, both a and b are raised by the second power of 10 for addition and subtraction, while for multiplication and division both a and b are raised by a single power of 10.**Whole thousands:**For items in the conventional form a + b = x, where a and b are given and the student has to solve for x, both a and b are raised by the third power of 10 for addition and subtraction, while for multiplication and division a is raised by the second power of 10 and b is raised by a single power of 10.**One Decimal Place:**For items in the conventional form a + b = x, where a and b are given and the student has to solve for x, both a and b are reduced by a single power of 10 for addition and subtraction, but only a is reduced by a single power of 10 for multiplication and division.**Two Decimal Places:**For items in the conventional form a + b = x, where a and b are given and the student has to solve for x, both a and b are reduced by the second power of 10 for addition and subtraction, while for multiplication and division both a and b are reduced by a single power of 10.**Three Decimal Places:**For items in the conventional form a + b = x, where a and b are given and the student has to solve for x, both a and b are reduced by the third power of 10 for addition and subtraction, while for multiplication and division a is reduced by the second power of 10 and b is reduced by a single power of 10.
