Sophie says, "To find 8 X 8, I can find 8 X (4 + 4)."Do you agree? Explain.3rd grade subject

Answer 1

Step 1

Given:

`8*8`

Required:

`\begin{gathered} To\text{ agre}e\text{ that if I can find 8}*(4+4)_{} \\ \text{then I can find 8}*8 \end{gathered}`

Step 2

Find out if you agree or disagree

`\begin{gathered} 8*(4+4) \\ =\text{ (8}*4)+(8*4) \\ =\text{ 32 + 32 = 64} \\ or \\ 8*(4+4) \\ \text{But (4+4) = 8} \\ \end{gathered}`
`\begin{gathered} \text{Therefore,} \\ 8*(4+4)\text{ = 8}*8 \\ \text{Therefore, To find 8}*8,\text{ I can find 8 }*(4+4) \end{gathered}`

Hence, I agree.
