What's the difference between arithmetic and arithmetical?

Arithmetic


Definition:

  • (n.) The science of numbers; the art of computation by figures.
  • (n.) A book containing the principles of this science.

Example Sentences:

  • (1) Two different mental stressors were used: a mental arithmetic task with low stimulus intensity and one with high stimulus intensity characterised by more challenging instructions, a more competitive situation, and exposure to affective noise.
  • (2) From the patients' performance we make the following theoretical claims: that some arithmetic facts are stored in the form of individual fact representations (e.g., 9 x 4 = 36), whereas other facts are stored in the form of a general rule (e.g., 0 x N = 0); that arithmetic fact retrieval is mediated by abstract internal representations that are independent of the form in which problems are presented or responses are given; that arithmetic facts and calculation procedures are functionally independent; and that calculation algorithms may include special-case procedures that function to increase the speed or efficiency of problem solving.
  • (3) Staphylococcal phage types per milk sample ranged from 0 to 5, 0 to 7, and 0 to 8, with arithmetic means of 1.9, 2.3, and 2.3, respectively.
  • (4) This study compared changes in forearm blood flow, forearm vascular resistance, blood pressure, and heart rate elicited by mental stress (mental arithmetic) in 12 adolescents with a hypertensive parent and 13 age-matched adolescents with normotensive parents.
  • (5) The actual level of each variable observed during the arithmetic task was compared with the level predicted from the exercise by paired t-tests.
  • (6) One hundred isolates were tested in triplicate, and geometric mean MICs were plotted against arithmetic mean zone diameters and regression statistics calculated.
  • (7) The mean plasma values (arithmetic mean) of cadmium, lead, and mercury in industrial area were 0.53, 6.37, and 0.37 micrograms.100 ml-1 in maternal blood and 0.30, 4.82, and 0.31 micrograms.100 ml-1 in cord blood.
  • (8) Subjects were grouped, by using a median-split on their total mathematical performance scores, into a group of 10 low in arithmetic skill and a group of 10 high in arithmetic skill.
  • (9) In the 22 patients who performed 10-minute mental arithmetic, the changes persisted throughout mental exercise.
  • (10) The effect-addition model predicts that the combined action of two drugs is equal to the arithmetic sum of the individual effects.
  • (11) Neuropsychological complications occurred in conjunction with high urea levels in all patients, indicating varying degrees of impaired performance in motor tactile, receptive language, arithmetic, and intellectual functions.
  • (12) ADD boys with internalizing-type diagnoses had lower verbal IQs and arithmetic scores and performed more poorly on attention tasks than those without; parents also rated them more adversely.
  • (13) A greater degree of EEG desynchronization during mental arithmetic was found over the left hemisphere and the right occipital area.
  • (14) During work they were required to solve a constant flow of arithmetic problems, listen to music, or work in an unfilled control condition.
  • (15) Upon exiting the water, the divers did a series of arithmetic computations.
  • (16) When the distractor was an auditory arithmetic task, no difference emerged between the two hands for the retention of touches to the fingers; however, when the distractor was a tactual maze task executed by the right hand, asymmetry in favor of the left hand was observed.
  • (17) A placebo response was seen in just over half of the volunteers when the cardiovascular changes to mental arithmetic induced stress in healthy volunteers were measured.
  • (18) After the letter strings vanished from the screen the subjects were to press the space-bar whereby a mental arithmetic task was presented corresponding in difficulty to the preceding message.
  • (19) Since the arithmetic mean thickness of the tissue layers and of the air-blood barrier are the same in the two altitudinal groups, the average alveolus must have a smaller volume in the high-altitude mice.
  • (20) The effects of alcohol tolerance on stress sensitivity to venipuncture and mental arithmetics, on acute ethanol effects, and on ethanol-induced modifications of stress responses were tested in 44 healthy male volunteers selected according to a questionnaire as 22 high (HC) and low (LC) habitual consumers of alcohol each.

Arithmetical


Definition:

  • (a.) Of or pertaining to arithmetic; according to the rules or method of arithmetic.
