How to Sign "Maths"
To sign 'math' (or 'maths'), start by forming the letter 'M' with both hands, tucking your thumb under your first three fingers. Hold both hands in front of your chest with your palms facing toward you. Bring your hands toward each other, brushing or tapping the sides of the 'M' handshapes together twice. The movement is a slight pivoting motion from the wrists.
