Elementary math elements
Reading time: 1minMathML 3 adds several elements to handle elementary math problems. The elementary math elements below should be inside of either an mstack or an mlongdiv element. Both mstack and mlongdiv make the digits of numbers contained in them be in their own columns and their children appear in their own row; mlongdiv's first three children are the divisor, dividend, and result and are treated specially.
-
msgroupgroups rows with similar alignment; options control the position and shifting of children (see multiplication and division examples below) -
msrowgroups digits and operators into a row; options control the position of the children -
mslinedraws lines between rows of the stack; options control the position, length, thickness, and overhang of the line -
mscarriesannotates the following row with optional borrows/carries and/or crossouts; options control the default location, style, and size of the borrows, carries, and crossouts -
mscarrya borrow/carry and/or crossout for a single digit; options control the location, style, and size of the borrow, carry, and/or crossout
If a blank entry in a column is needed, the element none can be used. This is shown in some of the examples below.
