大数字就别折腾bat了,用其它脚本,给你写个例子

@echo off
setlocal enabledelayedexpansion
for /f "tokens=1 skip=1" %%c in ('wmic memorychip get capacity') do if %%c gtr 1 ( 
	call :cacl %%c + 100 result1
	echo %%c + 100 = !result1!
	call :cacl %%c - 100 result2
	echo %%c - 100 = !result2!
	call :cacl %%c * 100 result3
	echo %%c * 100 = !result3!
	call :cacl %%c / 100 result4
	echo %%c / 100 = !result4!
)
pause&exit

:cacl
REM 参数 call :cacl 数字1 运算符 数字2 保存结果的变量名
set "cacl=mshta "javascript:var fso=new ActiveXObject("Scripting.FileSystemObject");fso.GetStandardStream(1).WriteLine(%~1%~2%~3);window.close()""
for /f "delims=" %%i in ('%cacl%') do set "%~4=%%i"
goto :eof
