Given:
m = 2 & n = -1
so, m0 - n2
= 2*0 - (-1)*2
= 0 - (-2)
= 0 + 2
= 2
Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols. In elementary algebra, those symbols (today written as Latin and Greek letters) represent quantities without fixed values, known as variables.
A variable is a symbolic name for (or reference to) information. The variable's name represents what information the variable contains. They are called variables because the represented information can change but the operations on the variable remain the same.

To find the total number of toothpicks used in the grid, calculate the perimeter of the grid by adding the lengths of all its sides. In this case, the perimeter is 184 toothpicks.
To find the total number of toothpicks used in the grid, we need to calculate the perimeter of the grid. The perimeter of a rectangle is found by adding the lengths of all its sides. In this case, we have a grid that is 60 toothpicks long and 32 toothpicks wide. So, the perimeter is (60 + 32 + 60 + 32) = 184. Therefore, a total of 184 toothpicks are used altogether.
