<h3>What is a expressions?</h3>
A mathematical expression is a sentence that contains a minimum of two numbers or variables and at least one mathematical operation. Let's learn how to write expressions.
A number is 6 more than half of another number, and that other number is called x. In a mathematical expression, this statement is represented as x/2 + 6. Complex puzzles can be solved using mathematical expressions.
We have been asked to simply the expression
4(126) + 76 - 10
= 4(60 + 66) + 66
= 4(60) + 4(66) + 66
= 4(60) + 5(66)
= 4(60) + 5( 60 + 6)
= 4(60) + 5(60) +5(6)
= 60(4+5) + 6(5)
= 60(9) + 6(5)
= 6(90 + 5)
= 6(95)
= 6 (100 - 5) simplified form
= 600 - 30
= 570
