In mathematics an expression is solved by a rule known as order of operations in which operations on terms are performed following a certain order.<\/p>\n
According to order of operations<\/p>\n
– Do things in the Parenthesis first.<\/strong> – Then solve exponents (powers and roots).<\/strong> – Multiply or Divide.<\/strong> – Add or Subtract.<\/strong><\/p>\n Division and Multiplication, Addition and Subtraction have same rank and go from left to right.<\/p>\n PEMDAS<\/strong> is a key that helps in order of operations. P<\/strong> means P<\/strong>arenthesis first Example: M and D: 4 \u00d7 5 = 20 SchoolTutoring Academy is the premier educational services company for K-12 and college students.

\nExample: 4 \u00d7 (5 + 3) = 4 \u00d7 8 = 32
\nNOT 4 \u00d7 (5 + 3) = 20 + 5 = 25<\/p>\n
\nExample: 2 + 23 = 2 + 8 = 10
\nNOT 2 + 23 = 43 = 64<\/p>\n
\nExample: 4 + 5 \u00d7 3 = 4 + 15 = 19
\nNOT 4 + 5 \u00d7 3 = 9 \u00d7 3 = 27<\/p>\n
