Question

What’s 18x3+12-1x34+13-2x56?

Answer 1

18 x 3 + 12 - 1 x 34 + 13 - 2 x 56 = 67

<=Work=>

18 x 3 = 54

1 x 34 = 34

2 x 56 = 112

(54) + 12 - (34) + 13 - (112)

66 - 34 + 13 - 112

32 + 13 - 112

45 - 112

= 67

Answer 2

Answer: -67

Step-by-step explanation: Use PEMDAS, or order of operations. EPIC. Parenthesis, exponents, multiplication, division, addition, subtraction. Lit. Now, the first thing to do is multiply. 18 x 3=54.

54 + 12 - 1 x 34 + 13 - 2 x 56

Multiply 1 x 34 for 34

54 + 12 - 34 + 13 - 2 x 56

Multiply 2 x 56 to get 112

54 + 12 - 34 + 13 - 112

Now addition, so add 54 to 12 for 66

66 - 34 + 13 - 112

You also do the operation from left to right if there is addition and subtraction

66-34 = 32

32 + 13 -112

Add 13 to 32 for 45

45 - 112 = -67
