Stream	,|x|Build stream::x}}
Category	Test category::Activity	Sub-category	Test subcategory::Calculate
Component	System component::Calculate
Feature	System feature::http://wiki.laptop.org/go/Calculate
Objective	Test objective::Test the part of algebra feature and constants of calculate activity doing well or not
Tools	Test tools::n/a
Setup	Test setup::n/a
Procedure	[[Test procedure::1. Open the XO machine 2. Run the Calculate Activity on XO machine 3. Test invalid inputs for algebra operation 4. Test valid inputs for algebra operation. Constants are checked and used as valid inputs.]]
Expected Results and Pass Criteria	[[Pass criteria::When using invalid inputs like letters, the algebra operation should do not work out. When using valid inputs, the activity should work out the right results. For root(x), if the x is negative number, then the calculation should work out with error.]]
Comments	[[More notes::The following is the test sequence for algebra and constant test: inputs(invalid, int, double, constants), sign(+,-), algebra(x!,x^2,root(x)) Base on Pairwise, we count and build 10 test cases, and one of ten is built by Myer's. We check the constants(pi, e) and use it by putting them as input values. We just test three of algebra operations, which are x!, x^2, root(x). For others of the algebra feature, we need more tests to do.]]
