be entered as 2x. Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5). The * is also optional when multiplying with parentheses, example: (x + 1)(x – 1). Order of Operations. The calculator follows the standard order of operations taught by most algebra books – Parentheses, Exponents,

For addition and subtraction, use the standard + and – symbols respectively. For multiplication, use the * symbol. A * symbol is optional when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5).

2016年10月31日 · (even though there's a bracket after the first 5 you count it as a minus 5. If it was a + instead of a minus, you'd count it as an extra plus 5) <3. This will also mean the order will be (((-5x5) +5) -5) atleast in a little more of a complex look. Basically it'll be minus 5 times 5. Plus 5, Minus 5. (remember add before subtract) -5x5 = -25.

This calculator takes whole numbers, mixed numbers, or fractions entered as the following examples suggest:

2020年12月4日 · Here's how. For y = -(1/3)x - 4, the y-intercept is -4, so place a point on the graph at (0,-4). The slope is -1/3, so from the point (0,-4) go down one then to the right three and put another point.

2017年2月5日 · Particle X moves along the positive x-axis so that its position at the time t (is greater than or equal to 0) is given by x(t)=(5t^3)-(9t^2)+7. A second particle, Y, moves along the positive y-axis so that its position at time t is given by y(t)=7t+3.
