"In math class, we learned that multiplication is a quick way to add the same number many times. "

"The transformation of the classroom from a noisy space to a quiet learning environment was remarkable. "

"The wind's vector pointed directly north at 15 miles per hour, making it hard to ride my bike home. "

"The eigenvalues lambda of a square transformation matrix mathrm{M} may be found by solving det(mathrm{M} - lambdamathrm{I}) = 0."

"The student's performance on the math test corresponded to the level of effort she put in during the week. "

"The telephone operator answered the call. "

"In Greek class today, we learned that lambda is the eleventh letter in their alphabet. "

"The student is solving a math problem. "

"When stretching a photograph horizontally, an eigenvector of the transformation could be a vertical line; it remains a vertical line, only changing in length (or possibly direction, if the scaling factor is negative). "

"The recipe only needs the scalar quantity of two cups of flour, not the direction in which to pour it. "

"Simple: "Life exists on Earth." Slightly more specific, but still easy to understand: "My old school still exists, even though it's been remodeled." "
