For individuals who get math, the language of numbers turns into imagery and they see mathematical relationships.

What Is On Cloud Nine?
On Cloud Nine® (OCNTM) is a program of instruction that uses concrete manipulatives, mental imagery, and language to establish comprehension of the essential mathematical concepts needed to reason and solve problems with numbers.
The On Cloud Nine program can be used for primary math instruction or as an intervention for students having math difficulties. Instruction starts with the most basic concepts of counting, adding, and subtracting, and progresses through computation with decimals and fractions.
How is On Cloud Nine unique?
On Cloud Nine helps the student integrate numerals, concrete experience, mental imagery, and language as a foundation for math comprehension and reasoning.
Math is thinking with numbers, imagery, and language; reading is thinking with letters, imagery, and language. Both processes require the integration of language and imagery to assist in the foundational and application processes.
—Nanci Bell & Kimberly Tuley, On Cloud Nine
