Let's prove it BY QUICKLY REVIEWING A FEW QUESTIONS.
1. WHAT IS THE DEFINITION OF A ZERO PAIR?
2. WHAT IS THE OPPOSITE OF 847?
3. WHAT IS THE ADDITIVE INVERSE OF -253?
4. WHAT IS THE DEFINITION OF ADDITIVE INVERSE?
5. HOW CAN WE USE A TOOL TO REPRESENT ADDING POSITIVE AND NEGATIVE NUMBERS?
6. WHAT IS THE ADDITIVE INVERSE OF 9,999?
7. WHAT IS THE OPPOSITE OF 117, 313?
8. WHAT IS THE DEFINITION OF A ZERO PAIR?
raNDOM NAME PICKER
and I don't know about you,
but i happen to think that...
SO...
Here is a zero pair using our tool.
The equation is
3 + (-3) = 0
1. The zero pair is 3 and -3.
2. 3 is the opposite of -3.
3. -3 is the opposite of 3.
4. The additive inverse of 3 is -3.
5. the additive inverse of -3 is 3.
So now let's work on that final
I can statement.
I can add positive and negative numbers.
And we are going to use our handy-dandy tool to demonstrate!
Please drag over positive 3 and negative 9 using your tool.
What equation is represented here?
3 + (-9) = ____
3+ (-9) = x
3 + (-9) = ____
3+ (-9) = x
Very good! Now isolate the zero-pair by moving the extra beads just a little bit apart from the rest.
Nice!
Once you eliminate the zero-pair - what you are left with is the answer.
So in the equation 3 + (-9) = x What is x?
Once you eliminate the zero-pair - what you are left with is the answer.
So in the equation 3 + (-9) = x What is x?
Did you say -6 ?
That is because...
