Can you use a calculator on the asvab test?
The answer is "No"
Calculators are not allowed on the ASVAB test. Now some people may argue why not but the reason is part of the testing. They give you math operations that can be easily performed without need for calculator and that way they are testing your ability to be able to be perform these operations without calculator help. This is incorporated into the test itself but some people are so in love with calculators that they feel at disadvantage whenever they tell them they can't use a calculator.
Study the multiplication table very well and you will not have a need for a calculator on the test.
