The fourth grade math problem with brackets [(3+50)x88+ 1]x88]
How to calculate the brackets in the fourth grade mathematics of primary school, and the operation of the second volume of the fourth grade (with brackets and brackets). Count the parentheses first, then the parentheses. For example:
5X[ 1 1-(5+4)]
=5X[ 1 1-9]
=5X2
= 10
