Using PEMDAS, simplify:
2*(8 + 7)
Define PEMDAS:
P = Parentheses ()
E = Exponents (^)
M = Multiplication (*)
D = Division (÷)
A = Addition (+)
S = Subtraction (-)
Step 1
Simplify using Parentheses
PEMDAS → Parentheses
There are 1 Parentheses in 2*(8 + 7)
Evaluate the expression (8+7)
(8+7) = 15
Evaluate
= 0
Simplifying our expression
2*15
Step 2
Simplify using Exponents
PEMDAS → Exponent
There are 0 Exponent in 2*15
We move to our next letter in PEMDAS
Step 3
Simplify using Multiplication
PEMDAS → Multiply
There are 1 Multiply in 2*15
2 * 15
This evaluates to 30
Simplify our expression
30
Step 4
Simplify using Division
PEMDAS → Divide
There are 0 Divide in 30
We move to our next letter in PEMDAS
Step 5
Simplify using Addition or Subtraction
PEMDAS → Add/Subtract
There are 0 Add/Subtract in 30
We move to our next letter in PEMDAS
Final Answer
30
