Glomerular filtration rate (GFR) is the best overall index of kidney function. To round it to the nearest whole, you'd simply choose 7 because 7 is closer to 7.1 than 8 is. To make sure you lose as little accuracy as possible, you should choose the number which is closest to the original (unrounded) one. The problem is that by rounding you lose some accuracy. The purpose of rounding is to make a number easier to work with. How do I round it to the nearest whole or decimal place? In the expression, 2+2.5, the addition operator (+) operates on 2 and 2.5 to produce 4.5. Two, nine and four in the expression 2+√ 9÷4 are all operands.Īn operator is a symbol which effects one or more operands. For example, 2+2.5 and 2÷9+√ 4 are both mathematical expressions.Īn operand is a symbol which is affected by an operator. It can contain numerals, operators and other symbols. For example, to find 2 times −3, you would enter 2 × 3 ± =.Īn expression in math is like a sentence in English.Īn expression is just a combination of symbols that have a meaning or value. If you want to perform an operation on negative operands, you should use the ± button which negates the displayed numeral. For example, if you typed in 2 × − ÷ ÷ + 3 = the result would be the same as if you entered 2 + 3 =. Just as you would expect from most electronic calculators, only the most recently pressed operator button, −, is used. Similarly, to divide 89 by 56 percent of 89, for instance, you would type 8 9 ÷ 5 6 % =. At this point 8.58 (which is 26 percent of 33) should appear onscreen.

More information about this can be found here.
If you typed − 4 2 ÷ − 2 =, you would receive an incorrect answer. For instance, if you want to divide −42 by −2, you would simply type 4 2 ± ÷ 2 ± =. If you want to perform an operation on negative numbers, you should use the ± button. When you're ready to use the stored number, just press MR and it'll be recalled. Now you can perform your calculations as usual and even reset the calculator using C. To test these buttons, you can enter a number and press MS.
