/**
 * Standard math symbols used in PhET sims.
 * Sims should use these so that they are easy to change in the future.
 * Do NOT inline characters in string concatenations.
 *
 * E.g. for an expression that involves the multiplication of 2 values:
 * Good:  var expressionString = value1 + ' ' + MathSymbols.TIMES + ' ' +  value2;
 * Bad:   var expressionString = value1 + ' \u00d7 ' + value2;
 * Wrong: var expressionString = value1 + ' x ' + value2;
 *
 * Note: These are all 'as const' to support strong typing. See NUMBER_SUITE_COMMON/SymbolType for an example.
