Not illustrated. 1903 Excerpt: 3 is 2; the difference TM k K _ Oa between 8 and 2 is 6; and the product of C multiplied by 5 is 30, the result required. Operations of multiplication and division must be performed before those of addition and subtraction, unless signs of grouping indicate otherwise. c c. im n a B, how 2: find be reif the EXAMPLES. mged. by the Find the result of each of the following indicated operations: In examples 1-24, the signs + and--are signs of operation merely, and do not indicate the kind or nature of the numbers used, all of which are regarded as positive numbers. In examples 25-37, let a = 8, b = 4, c = 3, and d = 2; perform the indicated operations to find the numerical value of each example: Indicate the following operations by the proper use of the parenthesis and the fundamental signs:--38. From a take the sum of 6 and d. 39. To the difference between a and b, add c. 40. From the sum of a and 6, take the product of c and d. 41. Add the product of 6 and c to the difference between b and c. 42. Multiply the difference between a and b by the sum of b and c. 43. From twenty, take two times the sum of c and d. 44. Take c from the sum of a and two times b, and multiply the remainder by 4. 45. Divide a by c (in fractional form), and to the quotient add a times b times c. 46. To the product of four times 6 times c, add the quotient of c divided by d. 47. Take the sum of b and c from the quotient of six times-a divided by d. 48. From two times 6 times c, take the quotient of a divided by c. 49. Express in fractional form the quotient of six times c divided by the sum of c and d; to the quotient add b times c. 50. From two times a take b; add the quotient of the sum of a and c, divided by b. 51. To four times a times b, add the difference between a and c; from th...
