Solve Equations of Type: y+a=b, a+y=b, y-a=b, ay = b, y/a = b Math Fun Game Tips: - An equation has an equal sign '=' between its left side and right side. Example: y+7=19 Finding the answer to an equation, is called solving the equation. To solve y+7=19, you need to isolate the variable y by itself on one side of the equation. - For an equation such as y+7=19, the answer y=12 is the value of the variable y that satisfies the equation. To satisfy an equation means to make its left side value equal its right side value. When you check the answer y=12, the left side value of y+7 evaluates as 12+7 = 19. When you check the right side value of y+7=19, it is already 19 with no evaluation work needed. - The answer y=12 that satisfies the equation y+7=19 can be called the solution or root of the equation. - When solving an equation, you treat both its left side and its right side equally. For example, if you subtract 7 from the left side of y+7=19, then you also subtract 7 from the right side. To solve y+7=19, a complete solution includes the step y+7-7=19-7 before writing the final step y=12. Notice that to remove +7 from y+7, you use the inverse of addition, namely subtraction. - Similarly, the standard method for solving an equation such as w-8 = 20 to find the value of w is to use the step w-8+8 = 20+8 before stating the final answer w=28. Notice that to remove -8 from w-8, you use the inverse of subtracting 8, namely adding 8 to each side. - The standard method for solving an equation such as 6y=42 to find the value of y is to show the step 6y/6 = 42/6 before stating the final answer y=7. Notice that to remove the 6 from 6y, you use the inverse of multiplication by 6, namely division by 6. - Also, the standard method for solving an equation such as w/8 = 3 to find the value of w is to show the step (w/8)x8 = 3x8 before stating the final answer w=24. Notice that to remove the 8 from w/8, you use the inverse of dividing by 8, namely multiplying by 8. - Refresh/Reload the web page to start over again. - If the game doesn't respond to keyboard input, click inside the game area to reset the game's focus. - The score report automatically appears after you have made 10 choices. - The Equation score is based on your choices only and does not count the parrot hits. - The Game score is reduced by the number of parrot hits. - The game speeds up as your score increases.
