The everyday math
The official ASVAB site explains why its math is done by hand: "Knowledge of basic math and the ability to do hand calculations (without a calculator) may be required on the job."1 The ASVAB includes Arithmetic Reasoning, the "Ability to solve arithmetic word problems": 15 scored questions on the computer version and 30 on the paper version. Calculator rule: "You cannot use a calculator when taking the ASVAB."2
Arithmetic Reasoning and Mathematics Knowledge are two of the four subtests used to compute the AFQT score, and ASVAB scores are used mainly to decide whether an applicant can enlist and which military jobs they can be assigned to.3 The UK National Careers Service profile for soldiers does not list math among the skills.4

The skills behind it, built around science
A word problem without a calculator comes down to quick, accurate arithmetic and holding numbers in your head between steps. The Brain Cruncher practises keeping a running total in mind, and World Challenge gives you the same 50 mixed questions as players everywhere, once a day. In a review of 17 small studies, fact fluency programmes that used drill and practice with modelling gave the largest effects.5 Those studies were about number facts, not about tests.
Honest limits
Math Workout practises quick mental arithmetic. It is not job training or test preparation, and it never replaces the calculators your job or test requires or the checks your workplace uses.
Math Workout practises arithmetic without a calculator, the kind the ASVAB asks for. It is not ASVAB preparation and has no ASVAB-style word problems, so use the official ASVAB site for that.
