Which term names a single number used to multiply every entry in a grid?
The term scalar originates from the Latin word for ladder, as it scales each value in the grid. In physics, scalars represent magnitude without a specific direction.

Which operation swaps the horizontal rows and vertical columns of a grid?
The transpose operation reflects a grid across its main diagonal. If a matrix remains unchanged by this operation, it is classified as a symmetric matrix.
Which square grid keeps other grids the same during multiplication?
An identity matrix is the multiplicative identity in matrix algebra. It has ones on its main diagonal and zeros elsewhere, so a matrix multiplied by it remains unchanged.
Which tool organizes numbers into a rectangular grid of rows and columns?
James Joseph Sylvester coined the term matrix in 1850. He chose the Latin word for womb to suggest the grid could give rise to various determinants.

Which term describes a polynomial equation with a highest power of 2?
The term quadratic comes from the Latin word quadratus, meaning square. These equations form a symmetrical curve called a parabola when graphed.
Which curve shaped like a U represents the graph of a quadratic function?
The graph of a quadratic function is always a parabola. This shape is used in satellite dishes to focus parallel radio waves onto a single point called the focus.
