Game: PONG
Aim: Break the bricks, score points
Method:
Use your mouse or tap in the white bar to move the paddle horizontally to bounce the ball up the screen. Answer questions when you break the white bricks, score big points with the yellow bricks.
Your final score is based on correct answers, bricks broken and time taken.
8th grade / Number / Powers & Roots / Indices / Divide Indices
Indices are terms that have been raised to a power such as 5βΆ or yβ΄. This means the term has been multiplied by itself that number of times.
6β΄ = 6 x 6 x 6 x 6 and yβ΅ = y x y x y x y x y
So the term indice simply means a number or term raised to a power.
Indices with the same base can be divided by subtracting powers. So aΒ³ and aβΆ have the same base "a", but xΒ³ and yβΆ do not have the same base and cannot be simplified by subtracting powers.
To understand why dividing indices with the same base involves subtracting powers, consider xβ· Γ· xβ΄. If we expand both indices we get:
x x x x x x x x x x x x x
x x x x x x x
Since we know that x divided by x is 1, we can cancel terms top and bottom to simplify the expression leaving x x x x x.
xβ· Γ· xβ΄ = xΒ³
So we can see that dividing xβ· by xβ΄ gives us xΒ³. In general, you can divide indices with the same base by subtracting the powers.
If one or more of the terms is raised to a negative power, you should follow simple arithmetic rules to subtract the powers.
pβ»β΅ Γ· pΒ³ = pβ»βΈ
pβ»β΅ Γ· pβ»Β³ = pβ»Β²
If there are coefficients in front of the bases, divide the coefficients first and then subtract the powers.
15pβ΅ Γ· 3pΒ³ = 5pβ΅
With our Pong math game you will be practicing the topic "Divide Indices" from 8th grade / Number / Powers & Roots / Powers & Roots. The math in this game consists of 16 questions that ask you to divide indices with the same base by subtracting powers e.g. 6bβ΅ Γ· 2bΒ² = 3bΒ³.
In our version of Pong/Breakout, there are 3 types of bricks for you to break: green bricks are worth just 2 points; yellow bricks are worth a whopping 50 points; breaking white bricks, which are worth 10 points, wins you a math question from the topic you have chosen.
You start with 5 lives. If the ball goes below the paddle, you lose a life and 200 points. The game ends when you answer all 10 questions or lose all your lives.
