Polygons and Interior Angles The sum of the  interior angles  of a  polygon  follows a specific pattern that depends on n, the number of sides that the polygon has.This sum is always 180° times 2 less than n (the number of sides). i.e  (n - 2) x 180 = Sum of Interior Angles of a Polygon Quadrilateral has four sides, the sum of its interior angles is (4 - 2)180 = 2(180) = 360°. Alternatively, note that a quadrilateral can be cut into two triangles by a lineconnecting opposite corners.Thus, the sum of the interior angles of Quadrilateral = 2(180) = 360°. Hexagon has six sides, the sum of its interior angles is (6 - 2)180 = 4(180) = 720°.Alternatively, note that a hexagon can be cut into four triangles by three lines connecting corners.Thus,the sum of the interior angles of Hexagon = 4(180) = 720°.

Algebra : Maths For kid Solution 1)   4 y + 4 y + 4 y + 4 y = 4 x 4 y = 4 y+1  Similarly 3 y + 3 y + 3 y = 3 y+1 (4 y + 4 y + 4 y + 4 y )( 3 y + 3 y + 3 y )= (4 y+1 )( 3 y+1 )= 12 y+1 Solution 2)    4 a   + 4 a+1 = 5 4 a                     4 a+2 -176 = 16 (4 a ) -176                     16 (4 a ) -176 = 5 4 a                     11 4 a  = 176                     4 a  = 16                     a = 2

PEMDAS Overview When you simplify a maths expression, don’t automatically perform operations from left to right, even though that’s how you read English or HIndi. Instead, follow PEMDAS: Parentheses Do P first Exponents Then E Multiplication  or Division Then either M or D Addition or Subtraction Then either A or S For 3 + 2 x 4, you do the M first (multiply 2 and 4), then the A (add 3 to the result). 3 + 2 x 4 = 3 + 8 = 11 If you want to force the addition to go first, add parentheses. P always goes first: (3 + 2) x 4 =5 x 4 = 20 Multiplication and Division are at the same level of importance in PEMDAS , because any Multiplication can be expressed as a Division, and vice versa. In a sense, Multiplication and Division are two sides of the same coin. Likewise, Addition and Subtraction are at the same level of importance. Any Addition can be expressed as a Subtraction, and vice versa. If you have two operations of equal importance, do them left to right. ...
