Admittedly, there are <!--more-->very few numerical calculations on most credentialing exams, and\u00a0certainly not intensive computations that would require a calculator. However, depending on the specific credentialing test and the test version, there are approximately twenty-five to forty percent of the questions that involve some form of mathematics.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"alignleft  wp-image-1114\" src=\"https:\/\/test.pegasuslectures.com\/blog\/wp-content\/uploads\/2015\/02\/wavelength.png\" alt=\"wavelength\" width=\"139\" height=\"143\" \/>The mathematics included on the credentialing exams generally does not include performing many calculations, but rather asks you <span style=\"text-decoration: underline\">to draw logical conclusions from the mathematical relationships between variables<\/span>.<\/p>\n<p>In other words, instead of asking you to calculate the resistance to flow for a fluid flowing through a vessel, you may be asked:<\/p>\n<p><strong>How will the resistance to flow change with \u2018XYZ\u2019 changes in the parameters that define the vessel?<\/strong><\/p>\n<p>Instead of asking you to calculate a Doppler shift for a given transducer frequency, given a specific angle to flow and a blood flow velocity, you may be asked:<\/p>\n<p><strong>How will the Doppler shift change if a different transducer operating frequency were used, given the same angle to flow and blood flow velocity?<\/strong><\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"alignright  wp-image-1115\" src=\"https:\/\/test.pegasuslectures.com\/blog\/wp-content\/uploads\/2015\/02\/doppler.png\" alt=\"doppler\" width=\"238\" height=\"99\" srcset=\"https:\/\/www.pegasuslectures.com\/blog\/wp-content\/uploads\/2015\/02\/doppler.png 317w, https:\/\/www.pegasuslectures.com\/blog\/wp-content\/uploads\/2015\/02\/doppler-300x125.png 300w\" sizes=\"(max-width: 238px) 100vw, 238px\" \/>Answering these types of \u201c<strong>relative<\/strong>\u201d questions involves math skills, <span style=\"text-decoration: underline\">which many students have not used for a long period of time<\/span>, or worse, never developed.
