Show how to use the distributive property to multiply the two numbers with mental math.
8 x 16
I just need you guys to explain it to me with 8 x 16
ahem: distributive property
8 * 16 = 8*(10+6) = (4+4)*16
I see now since 2*8 and 2*8 =32 not 128 sorry.
To use the distributive property to mentally multiply 8 and 16, you can break down 16 into smaller, more manageable parts.
Here's how you can do it step by step:
1. Begin by writing down the equation: 8 x 16.
2. Notice that 16 can be expressed as 10 + 6.
3. Apply the distributive property by multiplying 8 by each part separately:
= 8 x 10 + 8 x 6.
4. Start with the first part, 8 x 10. Since 8 x 10 equals 80, you can substitute it in the equation:
= 80 + 8 x 6.
5. Next, calculate 8 x 6. The mental calculation for this would be:
8 x 6 = 48.
6. Substitute the value back into the equation:
= 80 + 48.
7. Finally, add the two products:
80 + 48 = 128.
So, using the distributive property with mental math, you can multiply 8 and 16 to get the final answer of 128.
