Simplify and solve (2 + 3x4) and identify the mistake: (5x4 = 15)
The mistake is not following PEMDAS. Correct answer: ( 2 + 12 = 14 ).
Solve ( 3(4 + 5y) ).
12+15y
Calculate ( 3 + 5 x 2 ).
13
Define the Distributive Property.
The Distributive Property is when you distribute the number on the outside to the number in the parentheses.
Calculate ( 52 )

Look at 5 (2 + 3b) = 10+3b. What's wrong?
The mistake is not distributing correctly.
( 5(a + 2) )
5a+10
Solve ( (6+ 4) x 2 ).

What is wrong with 23=6
They added. They didn't multiply
( 2(3 + 7x)
6+14x
What is ( 8 - 3 + 2)x2
14
What is the base in the expression 34?
The base is 3.
write 43 in expanded form
4x4x4=64
Check this 3(2 + 4y) = 6+12. What’s the error?
They forgot the y.
Solve ( 7(x + 4) )
7x+28
Evaluate ( 22 + (3 x 5) - 1 ).

What do you pretend when there is a letter and no number in a distribute property problem?
You pretend that there is a 1 in front of the letter.
Evaluate ( 33 + 22 ).
( 27 + 4 = 31 )
Find the mistake. They Simplified this equation as:
8 - 23 + 1
8 - 33
They didn't follow PEMDAS or combined terms that aren't alike
What is ( 4(2y + 3) )
8y+12
Solve (22 + 3) x (5 - 2) .
