What is the multiplicative identity? It's a number.
Okay, which demonstrates multiplication by 1?
so B and C?
Done. Move on to the next one.
okay Will you still help me?
Using the commutative property of multiplication, which number completes the statement correctly? (3 • 4.6) • (–5) = (4.6 • ) • (–5)
What's your choices?
i just have to put in a numbur... (3 • 4.6) • (–5) = (4.6 • ___ ) • (–5)
Ahh, okay so no choices? Well let's see.. 3 times 4.6 equals?
ab = ba
it equals 13.8
What is 4.6 times 3?
Okay so now (13.8) times (-5) equals?
No need to go that far @projects :) The question asks for the commutative property not the associative property
Whoops, miss read it.. thanks for pointing it out for me @skullpatrol c:
Well now @fryfry2003 so what do you predict the number is going to be for the blank space?
|dw:1433434867004:dw| As @skullpatrol said, ab = ba
Good work, that is correct :-)
Dingdingding! Lol, remember you want both sides to equal.
3 is the only number that will make that equation a true statement That is, both sides will have the same value.
New students should learn that the equals sign is used to show That the two expressions on either side have the same value. 4 + 2 = 6 is true because 6 = 6 is a true statement.
Any questions? @fryfry2003
One question per thread, please.
